WO3 will it happen?

I read WW3 has already happened. Wikipedia has a good article.

Quote:The "War on Terror" that began with theSeptember 11 attackshas been claimed by some to be World WarIII[59][60]or sometimes as World WarIV.[54]Others have disparaged such claims as "distorting American history." While there is general agreement amongst historians regarding the definitions and extent of the first two world wars, namely due to the unmistakable global scale of aggression and self-destruction of these two wars, a few have claimed that a "World War" might now no longer require such worldwide and large scale aggression and carnage. Still, such claims of a new "lower threshold of aggression," that might now be sufficient to qualify a war as a "World War" have not gained such widespread acceptance and support as the definitions of the first two world wars have received amongst historians.[61]
