There is a notion (spread by Israel), that anything Israel does is justified and any that think otherwise are either anti-semites or terrorists. In the past, America has smuggled weapons to assist a downtrodden people that were being invaded by a much larger power. In this case, America is supporting the invaders. This does not make it right. If Iran is "smuggling" these puny little primitive rockets into Gaza, it is not enough. It is simply an annoyance to Israel. What Iran needs to smuggle is something that will change the game. Only this will lead to peace.
