Questions about war

Hello all. I am wondering several things. Can anyone tell me how many wars are currently going on in the world right now? I would also like to know what the difference is between a war and a conflict other than the size of the thing, or is that the only difference. Who is it that determines a conflict has progressed to a war ? One other thing can you direct me to a web site that shows me what wars are going on in the world currently? As I was typing I got to thinking that a conflict is a conflict and not a war unless you happen to live in the reigion where it is happening. Thanks Jane
