Israel does not have an ethical or moral problem with attacking friendly countries. During the 1967 war between Israel and Arab nations, Israel attacked USS Liberty in international waters, killing 34 Americans. USS Liberty was clearly flying the American flag in ideal conditions. This has been well established and NSA confirmed that it could not have been an accident. See here for relevant quotations. See also Chicago Tribune article New revelations in attack on American spy ship and an article by Washington Report on Middle East Affairs titled The Assault on the USS Liberty Still Covered Up After 26 Years.
See also the Lavon Affair. There are other similar incidents too.
As revealed in an interview with Alex Jones, approximately 11 months before the planes hit the buildings, Nicholas Rockefeller of the powerful and influential Jewish American Rockefeller dynasty told Aaron Russo there was going to be an event and out of that event 'we' would invade Afghanistan and Iraq. (source (@ ~26:48))
In October of 2000, approximately 11 months before the planes hit the buildings, a former Israeli Defence Force member named Andras Szekely overheard a conversation in Hebrew in the 'Jewish' 'Gomel Chesed Cemetery located at McCellen and 245 Mount Olive Ave. in Newark, NJ', in which one of the parties said 'The Americans will learn what it is to live with terrorists after the planes hit the twins in September.'; 'Don't worry, we have people in high places and no matter who gets elected, they will take care of everything.' and 'The Arabs are so stupid. They don't even imagine that we are using them.'. Andras Szekely eventually spoke with Special Agents Andrew H Stengel and Robyn L Gritz. All this was made known by Ed Haas of Muckraker Report who was interviewed by Alex Jones. Transcript.

The Wall Street Journal reported of "Zim American Israeli Shipping Co.16, 17": "All employees are safe. . . . Company moved most of its operations out of WTC one week before attack." (source)
American Free Press reported "Zim American Israeli Shipping Co., Inc broke the lease" and "Zim's WTC office space had been leased until the end of the year and the company lost $50,000 when it suddenly pulled out in the beginning of September". (source)
On 10 September 2001, the day before '9/11', an article by The Washington Times made known a SAMS (Army School of Advanced Military Studies) paper that said of The Mossad 'Wildcard. Ruthless and cunning. Has capability to target U.S. forces and make it look like a Palestinian/Arab act.'
As written about in Small Miracles for the Jewish Heart by Yitta Halberstam & Judith Leventhal, on the morning of 11 September 2001, a group of 'Jews' who worked in the twin towers got together to pray, but they were short by one (they required 10), which was very unusual. A man they did not know showed up and insisted on leading the prayer service. 'He seemed to rifle the pages of the siddur in agonizingly slow motion. Indeed, every gesture and movement that the man made seemed deliberately unhurried, protracted, and prolonged.' After this went on for a while, they heard the first impact, went outside to see what had happened and never saw the man again. He had saved them. (source)
ABC News reported that five Israelis were arrested for suspicious behaviour on that day: 'The men were taking video or photos of themselves with the World Trade Center burning in the background, she said. What struck Maria were the expressions on the men's faces. "They were like happy, you know ... They didn't look shocked to me. I thought it was very strange," she said. . . . The driver of the van, Sivan Kurzberg, told the officers, "We are Israeli. We are not your problem. Your problems are our problems. The Palestinians are the problem." The other passengers were his brother Paul Kurzberg, Yaron Shmuel, Oded Ellner and Omer Marmari.' (source) ABC News also reported that Maria said 'You know, they're laughing. They're laughing. One of them, I noticed, distinctively, put his hand on top of the other guy why they're filming, on top of his shoulder.' (source)
The New York Times reported of the Israelis: 'The five aroused attention in New Jersey after people noticed them going to unusual lengths to photograph the World Trade Center ruins and making light of the situation. One photograph developed by the F.B.I. showed Sivan Kurzberg holding a lighted lighter in the foreground, with the smoldering wreckage in the background, said Steven Noah Gordon, a lawyer for the five.' (source)
Ha'aretz reported of them 'The Foreign Ministry said in response that it had been informed by the consulate in New York that the FBI had arrested the five for "puzzling behavior." They are said to have had been caught videotaping the disaster and shouting in what was interpreted as cries of joy and mockery'. (source)
On Friday, 14 September, 2001, Fox News reported 'The New York Times reported Thursday that a group of five men had set up video cameras aimed at the Twin Towers prior to the attack on Tuesday, and were seen congratulating one another afterwards.' (source)
Former CIA agent Robert Baer said the five Israelis were 'probably Mossad', that 'they were set up before the first plane hit' and they were 'giving the high five after the World Trade Center was hit'. (source (@ ~4:35-))
Cui bono? (Who benefits?) Israel. When investigating crime, it is prudent to look at people who stand to gain. Report: Netanyahu says 9/11 terror attacks good for Israel. On 12 September 2001, The New York Times reported: 'Asked tonight what the attack meant for relations between the United States and Israel, Benjamin Netanyahu, the former prime minister, replied, "It's very good." Then he edited himself: "Well, not very good, but it will generate immediate sympathy."' (source)
Israel's oldest newspaper reported regarding Odigo (Israeli instant messaging service), 'two of its workers received messages two hours before the Twin Towers attack on September 11 predicting the attack would happen'. Odigo, bought by by Comverse Technology in 2002, had an office in Herzliya, the same area of Tel Aviv as The Mossad. (source)
In Decmber of 2001, Fox News correspondant Carl Cameron reported on Israeli espionage in United States. The story is available on YouTube (part 1, part 2, part 3, part 4). Transcripts are available here: Part 1, part 2, part 3. Part four is not available through archive.org, but you can get it and the other three here. Some interesting excerpts follow.
'investigators suspect that they Israelis may have gathered intelligence about the attacks in advance, and not shared it. A highly placed investigator said there are "tie-ins." But when asked for details, he flatly refused to describe them, saying, "evidence linking these Israelis to 9-11 is classified. I cannot tell you about evidence that has been gathered. It's classified information.". . .
Documents say they, "targeted and penetrated military bases." The DEA, FBI and dozens of government facilities, and even secret offices and unlisted private homes of law enforcement and intelligence personnel. The majority of those questioned, "stated they served in military intelligence, electronic surveillance intercept and or explosive ordinance units.". . .
HUME: Carl, what about this question of advanced knowledge of what was going to happen on 9/11? How clear are investigators that some Israeli agents may have known something?
CAMERON: It's very explosive information, obviously, and there's a great deal of evidence that they say they have collected - none of it necessarily conclusive. It's more when they put it all together. A bigger question, they say, is how could they not have know? Almost a direct quote.. . .
Fox News has learned that some American terrorist investigators fear certain suspects in the Sept. 11 attacks may have managed to stay ahead of them, by knowing who and when investigators are calling on the telephone. How?
By obtaining and analyzing data that's generated every time someone in the U.S. makes a call.. . .
Here's how the system works.. . .
But investigators within the DEA, INS and FBI have all told Fox News that to pursue or even suggest Israeli spying through Comverse is considered career suicide.
And sources say that while various F.B.I. inquiries into Comverse have been conducted over the years, they've been halted before the actual equipment has ever been thoroughly tested for leaks.. . .
And what troubles investigators most, particularly in New York, in the counter terrorism investigation of the World Trade Center attack, is that on a number of cases, suspects that they had sought to wiretap and survey immediately changed their telecommunications processes. They started acting much differently as soon as those supposedly secret wiretaps went into place Brit.'
Senator Bob Graham from the joint Senate and House Intelligence Committees seemed to indicate on The News Hour with Jim Lehrer that a foreign government was involved in the attacks: 'SEN. BOB GRAHAM: I think there is very compelling evidence that at least some of the terrorists were assisted not just in financing -- although that was part of it -- by a sovereign foreign government and that we have been derelict in our duty to track that down, make the further case, or find the evidence that would indicate that that is not true and we can look for other reasons why the terrorists were able to function so effectively in the United States.
GWEN IFILL: Do you think that will ever become public, which countries you're talking about?
SEN. BOB GRAHAM: It will become public at some point when it's turned over to the archives, but that's 20 or 30 years from now. And, we need to have this information now because it's relevant to the threat that the people of the United States are facing today.' (source)
Which foreign government's involvement is being kept secret?
In the December 20, 2002 edition of Executive Intelligence Review is the article Mossad Exposed in Phony `Palestinian Al-Qaeda' Caper. Danny Rubinstein reported for Haaretz on 7 January, 2006 that a man from Shin Bet was attempting to recruit Palestinians for 'Al-Qaida' and that 'Palestinian source said . . . that the case was not unusual' in the article Ibrahim, the Shin Bet wants you to join Qaida. In the BBC article Israel 'faked al-Qaeda presence', it is reported that the Palestinian Authority and Kenyan Colonel Rashid Abu-Shbak say Israel/Mossad is behind fake al-Qaeda presences.
On 13 September, 2001 Newsweek reported Pakistan's Maj. Gen. Hamid Gul's 'basic message is that Osama bin Laden is innocent, and that the attacks on New York and Washington were an Israeli-engineered attempt at a coup against the government of the United States'. (source)

On 11 September, 2004, The Middle East Media Research Institute reported that Egyptian intellectual Dr Hassan Al-Bana said of the attacks 'The scenario was prepared by Israel and the US.' (source)
On 30 November 2007, Italy's largest newspaper reported that lifetime Senator and former President of the Itallian Republic Francesco Cossiga said 'all the atmospheres democratics of America and Europe, with in front line those of the Italian centre-left, know by now well that the disastrous attack has been planned and realized from the American Cia and the Mossad'.

On 15 March, 2010, Dr. Alan Sabrosky (Ph.D, University of Michigan), former Director of Studies at the US Army War College said in an interview 'What we need to stand up and say is 'not only did they attack USS Liberty; they did 9/11. They did it.' I am. I have had long conversations over the past two weeks with contacts at the Army War College; at the headquarters, Marine Corps, and I have made it absolutely clear in both cases that it is 100% certain that 9/11 was a Mossad operation. Period. You know, and you know, Phil, I don't denigrate what happened to USS Liberty in the slightest, you understand that. But for most Americans, you know, what happened to the USS Liberty or in Vietnam was history. You know, this is history. You know, they can be concerned about it, but they're not going to get mad about it. 9/11 has led directly to 60,000 Americans dead and wounded. God knows how many hundreds of thousands of people in other countries that we've killed or wounded or made homeless. And it's an ongoing sore; it's not your sore from the USS Liberty, it's not my sore from Vietnam; both of us have those; both of us care about it. But this is an ongoing, this is an open wound and what Americans need to understand is they did it.' Part 2 (the relevant part starts at 8:35). Part 3.
