There are zero possibilities that Israel did not see that attack coming. They are the foremost intelligence agency in the west. Which means it was allowed to happen to justify what's happening right now.

Israel is not an innocent bystander that just had to defend itself. There are plenty of Orthodox Jews opposed to the current war and Israel's conduct in the region. I'm not an expert, but I'm open to the insights of those that live there and have a different opinion than the typical "Israel does no wrong". There is not a consensus among all Jews here or there.

To claim that people who disagree with the carnage are somehow either leftist, stupid or responsible for the perpetual conflict is intellectually dishonest. 

I love my family. I stand with my family. I support my family.  But sometimes they fuck up and are the asshole in a situation. When they do, it's only proper to tell them so. That's where Israel is right now. No excusing what's happening.
