Because now the manifestation of all this crap has reached a nuclear stage of undeniability.

It has literally been simmering for a long time and now it finally comes out. Taking it out on Israel is not wrong and that's not to say that they (the Israeli government) hold the sole responsibility for this. The US had a say in this as well. But now the US is questioning the benefits of this complete and total asshattery and rightly so. Better late than never I suppose.
