In October 2004, at the European Social Forum in London, an Israeli air-force pilot, Yonatan Shapira, called for sanctions against Israel. A year earlier, Shapira had refused to bomb Palestinian towns and had influenced 26 of his comrades-in-arms to do the same. He spoke of his love for his country and of his conviction that it was on the road to self-destruction. He had come to London to ask for help. Europe was Israel's only hope, he said: it must impose sanctions on his country and force it to make a real peace. About 3,000 people were on their feet cheering him.

And yes, I support Israel's right to exist within the 1967 borders.
