You want some proof Operation Northwoods ....now Say "Northwood" 3 times fast. lol

https://en.wikipedia.org/wiki/Operation_Northwoods

The government would never attack its own country to create a false flag to invade another country. And they would never assassinate any president who refused to kill innocent civilians.... its not like there are any government documents planning to commit acts of terrorism on us citizens, to provide justification for war. What is a false flag? Why would anyone even come up with a term like that?
