While there surely is reason to criticize Israel on many levels I don’t understand what people like you expect what Israel or any other state would do if there was a group (Hamas, which is designated as terrorist by many Democratic countries) raiding it’s territory and kills and kidnaps a number of it’s citizen.
just to put in relation 1.400/10.000.000 Israelis would equal 46.000 USA citizen (333.000.000 inhabitants). when applying this scale this would be much worse than 9/11.
Again, I think Israel should rightfully be criticized for many things, but clearing out Hamas makes sense when viewed as it’s own topic. And looking at the number of high civilian casualties in Gaza they are being criticized even by the USA, you still have to consider that Hamas are hiding in civilian infrastructure on purpose to use them as human shields. Also while the numbers of casualties in Gaza are being reported from inside Gaza you would not know how many of them are actually part of Hamas. They won’t give you this information.
Anyway, the whole middle east is fucked up and I wish that they could finally all live in peace and ditch their religious fanaticism so the few can not exploit the religious for their fascist cause whether it be Muslim, Christian or Jewish.
