If everyone was Buddhist there would be no wars whatsoever.
Thats the kind of attitude that I call Dawkinsism. If that were true, medieval east asia would've been a paradise on earth, southeast asia wouldn't have been the home of Muay Thai, and the Burmese government wouldn't be one of the most violent military dictatorships on the face of the planet. Its grossly misleading to judge people on the basis of their religious beliefs, or a religion from the acts of the people who claim to practice it.
On the other hand, the Buddha did encourage more independent and rational thought than most religious figures:
"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense."
"No one saves us but ourselves. No one can and no one may. We ourselves must walk the path."
"I do not believe in a fate that falls on men however they act; but I do believe in a fate that falls on them unless they act."
etc.
Edit: Though you do have to ask what kind of buddhists the Burmese officials are, beating, imprisoning, and torturing the monks who supported the recent democratic uprising.
