What happened with respect to the cold war with respect to 1987 the year?

The key to your question is the fact that you asked if the U. S. government had "no involvement" in the 9-11 tragedy. Most people seem to jump to the polar opposite sides in this debate. Either you believe the government planned and committed the assault, or you think that everyone of that opinion is a crackpot and believe the government's explanations about what happened that day. I think the answer is somewhere in between. I find it difficult to believe that the U. S. government would plan an attack of that magnitude on its own people because there's far too much to lose. There's no doubt that there'd be a full-scale revolution by the people if the government was proven to be the masterminds of the event. In fact, you probably wouldn't even have to prove it beyond a shadow of a doubt. If enough evidence came out to make it look very likely, there'd be a very serious problem in the U. S ... Having said that, there are too many questions that have not been answered by the government - or the answers that they've provided are very weak and unbelievable. What makes matters worse is that the government has been attacking those who ask questions, linking all doubters to terrorist sympathizers. That kind of attack on free speech is dangerous and should never be trusted. I've always had a funny feeling that the 9-11 attacks are a combination of terrorist hatred for the U. S. and corruption by the Bush administration. I think that the terrorists hijacked planes and intended to hit the World Trade Center. I also believe that the government knew that the attack was coming, but did nothing about it. The attack gave the U. S. an excuse to expand its military and political activities in the middle east.
