well...
Israel entered the camps in order to kill terrorists in them.
Many terrorists were killed, a factory of missiles was destroyed, 15 missiles captured.
unfortunatly, some civilians were killed too (you already know why, here's a reminder...)
a suicide bomb exloped in a center of a town, he terrorist tried to kill AS MANY CIVILLIANS AS POSSIBLE, (unfortunatly, did I mention?)
as to france, next decade, when muslims will rule their country, they'll understand, but it will be too late for them.
why do you take france as a reference agains israel, they are well known in their pro-palestinian (aka the underdog) attitude.
