Other than the attack on September 11, 2001, there was the attack on the USS Cole in Yemen. There have been to numerous attacks on our embassies. Not to mention the atttacks on our allies. London, Paris, Brussels and Madrid have all been attacked. That is all the ones I could think of just off the top of my head.
There is no war on terror. It is a concept created by leaders to bring in a New World Order. The same idea, centuries old.

Some like this one need help.
That's why we are here.
