It is quite obvious that Barak is blissfully oblivious to the heavy irony in that statement regarding "...envisioning a nuclear Iran that intimidates its neighbors and legitimizes radicalism and terror.“

In the neighborhood of the Middle East, it is Israel which intimidates its neighbors and legitimizes radicalism and terror, particularly for Palestinians having to deal with intimidation and physical violence from settlers living on illegal settlements, not to mention the IDF.

It is Israel which will not allow the siege of Gaza to end.

It is Israel which refuses to define its borders in order to obtain a meaningful peace with the Palestinians.

It is Israel which continues to harass Lebanon, with illegal overflights to which the IDF is hoping the Lebanese military will respond, so that they have another excuse to go into Lebanon, all the way to the Litani river, because they want to claim the water as its own.

It is Israel which has nuclear weapons, as confirmed by the revelations of Mordechai Vannunu in the late 80s, and by both former Israeli Prime Minister Ehud Olmert, and former American President Jimmy Carter.

It is Israel which urged the US to invade and occupy one of its former "existential threats in the region", Iraq. The Iraq war was built on a pack of lies with which to "sell" the war to the American people; now, Israel is trying to do the same thing with Iran.

It is Israel which believes that its Mossad can carry out extrajudicial assassinations everywhere in the world with impunity, as evidenced by the recent "hit" on Mahmoud al-Mabhoud in Dubai.

It is Israel which takes territory by any means they think they can get away with, as evidenced by the recent declaration of "heritage sites". As reported on 25 February 2010 in:

http://www.jweekly.com/article/full/41481/soldiers-clash-with-upset-palestinians/

"At a special Cabinet meeting Feb. 21, Netanyahu announced the plans for the Cave of the Patriarchs in Hebron, as well as Rachel’s Tomb on the outskirts of Bethlehem, to be added to a list of national heritage sites that Israel will rehabilitate and promote. Altogether, about 150 sites are on the list."

"The Palestinians claim all of the West Bank as part of a future state, and see the Israeli move as a provocation. In fact, Palestinian President Mahmoud Abbas, speaking Feb. 23 during a visit in Belgium, warned that the region could plunge into a “religious war.” '

it is Israel which is the ultimate "bad neighbor" in the Middle East, not Iran.
