Vatican City- we know they have a nuclear arsenal somewhere there
Switzerland- they're too peaceful. Obviously a trick. No one will see it coming when they nuke Greenland
Greenland- their 5000 inhabitants are all neo nazis willing to die for the motherland. No one goes there, so no one can prove me wrong.
Swaziland- their primitive technology is so old we won't be prepared. They'll wipe over the world
Iceland- we all know they're working on a Death Star as we speak. It's only a matter of time before Obama becomes their Darth Vader
Anartica- when it becomes a country, they'll obviously elect superman as their president. He's bound to cause some conflict.
US is quite aggresive. North Korea is poor, because much of its money is used on Nuclear weapons, and their dictator leader threatened to bomb up Japan and South Korea. If they do, the war begins. Japan, well, they lost in the 2nd world war and they can't have an army. But they are applying for an army. When the day they have an army (they might even be forming one behind all our backs), the war begins.
