The Moon!
We (The West) should declare that the moon, and all its deposits of Cheese belong to us!
mmmmmmm Moon cheese.
I'll go out on a limb and predict that the someone starts calling the United States' slowly ever-increasing presence in the slowly ever-disintigrating Mexico a war.
"In today’s America, conservatives who actually want to conserve are as rare as liberals who actually want to liberate. The once-significant language of an earlier era has had the meaning sucked right out of it, the better to serve as camouflage for a kleptocratic feeding frenzy in which both establishment parties participate with equal abandon" (Taking a break from the criminal, incompetent liars at the NSA, to bring you the above political observation, from The Archdruid Report.)
I'm going with Canada vs Russia over the artic region. US helps Canada not because they really like Canada but because they hate the Russians. It turns into a very slow war as the armies can't find the other side in the snowstorms. Both sides then say fuck it and go home due to the cold leaving the people of Antarctic to take it over.
Canada should be next. You can just tell that they're up to something.
Ironically, a war between the super-rich and the rest is probably the only war that makes real sense in our future.

No, no. We're just playing hockey and brewing beer - pay us no mind - we're just silly Canadians with funny hats and funny accents ^^

If US&China went to war, chances are it would be the end of the world. Other countries would step in as ally for both sides...nuclear blah blah blah, we wouldn't wake up one day. Just how it is. I try not to think about 'what will be the next war' it's inevitable that we will be in another war at some pointin the future, but until then, lets just be happy that we are at a calm point.
