ISOLATIONISM: Yossi Klein Halevi has another great article in TNR regarding the consequences in Israel of near-total international condemnation. One point is particularly noteworthy:

A benign or at least neutral international climate is a key precondition for Israeli willingness to take risks for peace. Though it's widely assumed that the Oslo process restored Israel's diplomatic standing, the sequence of events was actually the opposite. Only after the former Soviet bloc, China, India, and much of the Third World renewed diplomatic relations with Israel in the early '90s, following the Gulf war and the collapse of the Soviet Union, did Israel feel safe enough to begin negotiating with the PLO.
...International detractors who turn every Israeli act of war into a war crime and subject the Jewish state to a level of moral judgment not applied to any other nation are inciting the very hard-line forces they deplore.
