It is always different when a foreign group kills children/starves over extended time like Israel did to Palestinians, as opposed to a dictatorship (think Syria before its revolution succeeded or Iran right now) kills their populace.

Think just of how hard it is to cover Israel/Palestine given Israel's ban on journalism and a free press covering Ghaza. Now imagine a nation as big as Iran where the state controls the media. How do you expect accurate coverage in a matter of days
