Hamas hides its missile launchers in schools, mosques and hospitals making killing civilians and children unavoidable.
Yes, they absolutely do, I am not sure how you could deny this statement. And I am not sure how you could blame Israel for firing back. I dont care how progressive you think you are, if someone is shooting rockets on your town and family and kids, anyone, even the Quakers, would scream at their government to obliterate wherever those rockets are coming from.
Here is another question that is in the same sort of moral category, If we knew the intentions of the terrorist who hijacked the planes on 9/11 before they hit the towers, would it be justifiable to shoot those planes down and save 1000's of civililian lives through sacrificing a couple hundred civilians lives?
