Short Wars
Consider the following quote and place your thoughts:
"The belief in the possibility of a short decisive war appears to be one of the most ancient and dangerous of human illusions"
-- Robert Lynd (1879-1949), Anglo-Irish essayist, journalist
I think in the olden days a war could be short and decisive. I do not believe such a war can happen nowadays. Maybe if a bunch of nations came together to put down one nation it could happen but it would take some time to prepare for the invasion. So no I do not think a short war will occur on earth again. Or at least until after WWIII.
