Israel, it's about time!

In that second part I disagree with you though, proportionality has a lot to do with the end result.

Too bad international law doesn't agree with you. The military value of a target determines the proportionality.

But anyway, indifference for the end result is a form of intention.

Israel is not indifferent. If it was, it would just destroy the entire Gaza strip over night and be done with it.

If Israel did all these attacks without knowing that civilians would be killed and if these civilians were not considered "acceptable losses" the attacks would have ended a long time ago.

Acceptable losses are determined by international law. The higher the military value of a target the more it is acceptable to hit it, despite the risk to civilians. Remember you can't guarantee 0 civilian casualties in a war.

By doing these kinds of attacks on civilians Israel shows a contempt similar to Hamas's. I fail to see why two acts of terror are better than one.

Israel doesn't attack civilians. It attacks Hamas. Civilians regrettably die in the process because Hamas ignores international laws and keeps them around as human shields.
