I would say it is becoming somewhat irrelevant who 'backs' Israel in the long run. And while we all rant and rave and scream about the utter vile hypocrisy that is the UN, who are they? What do they really accomplish? Would an Indian-Chinese-Israeli defense and economic partnership, in addition to Italy, Singapore, Colombia, Brazil sit idly by as Israel, a major partner in their high tech, space, weapons industries as well as a major trading partner was ground into the dirt? I don't think so. In fact I would like to see more and foreign (non Western) students enroll in the advanced university programs in Israel in medicine, materials science, agriculture, engineering and high tech fields. BTW, right now, today, the talented foreigners are fleeing the US in one of the biggest brain drains in the US ever. The economy is broken, the political climate for foreigners is poisoned and there aren't any jobs for them. It would be wonderful if some of them came to Israel.
Ah..... and the brain drain from Israel is also tremendous. Israel is very much dependent on USA and all those Singapores, Indias and Brazils can very much do without Israel. So they would buy from someone else...
