Yet note that his article, like most pieces that seek confirmation that the boycotters are beginning to hurt Israel, never gives numbers. Ultimately it's an economic matter, after all: can Israel be made to hurt so badly that it makes a difference. So you'd think the boycotters would have a big chart with numbers: the size of Israel's economy, stats on various segments of it, targets that need to be reached so as to make a difference - that sort of thing.
But of course there is none of this. As even Beckerman sort of admits, the boycott movement is fundamentally about having a world without Israel; if that's the goal, the boycotters might note that the Jews have faced much worse foes in the past, and from abysmally worse starting positions.
So far, 2009 is proving less of a problem for Israel's economy than for most developed countries. (See the various financial and economic indicators of The Economist).
Then, of course, you've got the ludicrous aspects of the movement:
Ironically, Barghouti, who appears to be one of the movement’s chief strategists, is currently in a master’s degree program in philosophy at Tel Aviv University — even though he is one of the founding members of the Palestinian Campaign for the Academic and Cultural Boycott of Israel. He has been one of the activists strongly pushing the greater BDS movement in the direction of opposing any institution associated with Israel. Asked about his affiliation with an institution he wants boycotted, Barghouti declined to discuss his personal life.
