I guess the Balkans will have to fend for themselves now. They are going to have to go back to killing each other, since they aren’t killing foreigners. Perhaps they’ll even rethink their actions and try peaceful coexistance for the first time in a couple hundred years.
We’re going to need troops to implement all these military options. There are thousands of them sitting around on various peace-keeping missions. I’m saying that they are going to be recalled, and all those former trouble spots are going to be left on their own.
You’re jumping the gun a bit, since no decision has been made about what to do militarily (or if it has, nobody has reported massive military movements).
Where are all these troops needed? I don’t recall war being declared on a country.
