They have made it so that works wide wars like WW1 and WW2 most likely won’t happen again because of possible use of WMD’s (weapons of mass destruction). They created peace in WW2 because otherwise many more Japanese civilians would have died, as well as American soldiers. The Japanese leaders weren’t surrendering, and the conflict needed to end. The world is more dangerous now because of the sheer amount of WMD’s that exist. It would only take 40 nukes to put the entire world into a nuclear winter, and the US alone has over 1000.
