False flag terrorism

False flag terrorism is a means to result in wars.911 was an example.The government of the USA wanted to catch up Osama ,who hated the culture in Western and organized a terrorism group. So the government made some fake attack at 9/11 like Pentagon and the building 7. Then they said it's all the terrorism done.

After I see this video , I feel not good about that . Although the government want to fight with Osama ,they don't  need to use this way to hurt their own people. Perhaps there is a better way to solve it.
