Killing women and children?
According to your logic, wouldn't Hamas also be justified? You don't think it's morally wrong.
Israel never targets women or children.
Hamas, on purpose, puts women in children against their will as human shields. THAT is morally wrong.
Hamas has kept many civilians, actual civilians and not Hamas supporters from fleeing south for safety and use them against possible Israeli strikes, or just for counting them as dead when Israel has the right to target a place being used as a military base by Hamas.
ANY place used by Hamas as a military base, is a Military target according to International Law.
There is no way, in any war, that there are not going to be civilian casualties. But in many other wars around the world, civilians are not put in danger, to die, by their own military fighters so that a civilian count will bring sympathy to them.
Israel LEFT Gaza, the small part it had, in 2005.
Hamas is justified about nothing since it chose since 2007 to continue to attempt to destroy Israel launching rockets after rockets, and starting wars every few years.
Will Gaza without Hamas and Islamic Jihad finally become what it should have become from 2005 on?
