If Israel wasn't ruthless, they would have been conquered 70 years ago.
I see "Israel was involved in the creation of Hamas." as an excuse for every bad thing Hamas did since then. That's not valid logic.
Instead of letting foreign aid get smuggled to Hamas, maybe the people who wanted to help the people should have been organizing an opposition group to Hamas?
If Israel followed the same morality as Muslims, all the Palestinians would have been dead a long time ago.
