The ships were intercepted in international waters, you do know that right?
Thats like going over to the guy when he's a block away from your house and shooting him.
Plus thats a bad analogy, how can Palestinians - Israelis be like brother and sister?
You could have made a better analogy by saying, that a thief who has broken and entered into a guys house a long time ago and has a blockade imposed on him, not allowing basic things like food and water in, then come a few people who want to help the rightful owner in the house, the thief, incensed at their desire to help the owner goes over to the street, before the helpers even reach the house and shoots at them.
