I disagree with the, ‘central understanding,’ that Israel would be lost without American Jews. Israel benefits from that support; but the seeming necessity of which, is simply a method of sustaining it.
1. Palestine was chosen as the location for the Jewish state, simply from nostalgia. In considerations of defense and industrial self-sufficiency, almost impossible to have chosen a more stupid spot. So yes, of course, Israel’s vulnerable. And it’s true, the US has subsidized Israeli defense; but Israel can and would pay for its own defense, regardless. Their high taxes would just get a little bit higher. As for the UN, Israel would continue to ignore UN resolutions, even were the US disinclined to run interference.
2. US support doesn’t depend on a united Jewish consensus. It depends on rich and powerful lobbies, thinktanks, media, etc; funded by a handful of billionaires, and a hatful of millionaires; and doesn’t require the support of even a simple majority of American Jews. Jewish Zionists are dwarfed by the number of Christian Zionists, so it’s Jewish money, and Gentile votes, that Israel’s banking on; not Jewish votes.
3. It’s the campaign-benjamins, and other perks, that will continue to influence those politicians w/out spines. There may be a few who would feel more space to differ, if there wan’t a united front; but not enough to make much difference in policy.
Israel is finding plenty of allies and trading-partners, out in the world, less ideologically democratic, so more naturally sympathetic, than the US. No, Israel doesn’t need the USA; but only wants to keep the milktrain running, as long as possible; knowing that Western nations, however naive, will eventually catch on. What’s really at stake, is the loss of status, of American Zionist Jews, in the eyes of Israeli elites. Zionist Jews fear losing in importance, to their foreign homeland.
