Actually a nuclear terrorist on say New York could lead to World War III. What if Iran get its hands on a nuclear bomb? What if we could have stopped Iran, but we didn't because we listened to the French and the Russians? The Iranians build their bomb and they destroy New York. The United States then launches missiles at Iran and North Korea suspecting one of these two culprits but attacking them both so that none escape. The French and the Russians do not escape retaliation as it was because of them that Iran got nuclear weapons in the first place. A nuclear exchange then takes place between these three countries, all because the were trying to contain US power by impeding US efforts against nuclear weapons proliferation. In the end we all go down. the surviving French and Russian attack Americans on sight and the same hold true of anyone caught speaking French or Russian on US soil. Various warlords take control of the countyside and few countries escape. New Zealand is one exception, someone forgot to nuke that country.
