People misuse the term "World War" because we've forgotten the scope of WWII. What we've lost in ten years of war is a drop in the bucket compared to single battles fought during WWII. Entire companies were wiped out in less than 20 minutes. The fight was everywhere, on almost every continent. Asia, Africa, Europe, and to a small degree, North America. That really isn't feasible today, because the biggest military powers all owe each other money, or they are so intimately bound with trade deals that to start a war would be financial suicide.
However, if I were to pick a country that would go bat-**** crazy and rekindle militant nationalism, I would, unfortunately, have to say it would be the US. Politics are steadily becoming more radicalized, and extreme-leaning leaders are exploiting the current economic situation. Sound familiar?
Iran will likely get some more sanctions laid on them, and, worst case scenario, maybe an airstrike, though I have no idea what that would accomplish.
The weakest of all weak things is a virtue that has not been tested in the fire.
