There is no international law, there is only "power" in this world if you are strong enough to do whatever you want -- you will always get away with it, the human rights and all the rest of it are just pure propaganda to feed the average joe.
As for the hospital blast, the Western media already has the plan to justify that given that the majority of their audiences are brainwashed, they could claim that this was done by Hamas on purpose or by mistake, they could also claim that Hamas was hiding rockets under that patients' beds, and those folks will happily accept the death of all those civilians and continue to send their hard-earned money in form of taxes to Israel because somehow, they think that if Israel is gone, the next target will be their country, and surprisingly this is common western propaganda, because the Americans think the U.S will be next after Israel, and so do the French and the British and everyone else who supports Israel, it's like the Palestinians have some secret nuclear weapon which will deploy to erase the whole world and the only thing standing in the way of that magical bottom is Israel.
