How about banning Israeli politicians for supporting terrorism? http://mondoweiss.net/2011/04/how-about-banning-israeli-politicians-for-supporting-terrorism.html

Israeli leaders have condemned the nascent Palestinian reconciliation, considering the possible participation of Hamas members in any government to be unacceptable because of the party’s history of terrorism. To the great surprise of no one, American politicians have been competing for press attention to parrot the same line. What if Palestinian leaders, and our own Congress, did likewise, and demanded that Israel bar from elective office any member of a political party with a history of engaging in or supporting terrorism? Of course, a full recital of Israeli attacks on civilians would fill a multi-volume treatise, but let’s content ourselves with a thumbnail sketch. First, consider Labor, the most liberal/left of Israel’s major parties. Anyone who supported the great peacemaker and Nobel laureate Yitzhak Rabin would be barred.
