The tiananmen square massacre was a response to?

The Tiananmen Square Massacre was a military attack on unarmed civilians protesting against economical changes introduced by Deng Xiaoping (focus on material prosperity instead of ideological purity). The government had hidden many facts about the bloo dy riot, so today there are many unexplained aspects - like the amount of victims, ranging from a few hundreds to a few thousands. It took place on 3-4 June of 1989.

I think to a degree we should have. In WWII I think entering the war was necessary after Pearl Harbor, but nowadays I think we need to focus on America first, and stop worrying about every little thing in other countries. America has a lot of problems it needs to fix, and pulling out of other countries affairs would be a good way to do so.
