Is the US going to have a world war?

There is a possibility we were talking about this in school. Many places are shutting down their internet to try to show independence in freedom including places like Saudi Arabia, china, of course Egypt and even more in Europe, Asia, and Africa! So us being connected to them, if they overthrow their government they may dislike America causing a fight. This all will create a chain reaction. Everybody will fight! We are all connected in one way good or bad. thanks also, I'm in middle school... im pretty sure about my answer but get more incite thanks. adiOS
