HAHAHAHA! The '67 war is the land mark case of preemptive attack (by Israel).
One wonders if it had anything to do with this:
In May 1967, Egypt's president Nasser expelled the United Nations Emergency Force (UNEF) from the Sinai Peninsula. The peacekeeping force had been stationed there since 1957, following a British-French-Israeli invasion which was launched during the Suez Crisis.
Egypt amassed 1,000 tanks and nearly 100,000 soldiers on the Israeli border and closed the Straits of Tiran to all ships flying Israeli flags or carrying strategic materials, receiving strong support from other Arab countries.
Of course Egypt has all the right to do all this aggressive behaviour
But for Israel to do it?!?!?! DAMN THATS TERRIBLE!
