If you drop a 2000lb bomb in a refugee camp with the intent of killing your enemy leadership, full well knowing thousands live in the exact same space, is your intent only to kill a couple specific people?
If you are an enemy leader hiding in a refuge camp you are excused from culpability tho?
Point being Israel doesn't attack that refugee camp unless there is a military target there. Hamas is there because it gets that exact reaction you posted and then they win despite slaughtering innocent Israeli citizens a few weeks before as well as those refugees. This is how they divide and conquer other people.
This is how you wind up like a Palestinian being represented by brutal fanatics who would use your kids as human shield to advance their absolute control over you and your family. It's how you wind up being slaughtered at worship of another religion because you are an infidel.
So think carefully about who you are dealing with before you side with a brutal regime. AKA, don't eat the cheese.
