First, let's clear something up: The United States is the biggest geopolitical player on the world stage; everything that happens on it is our business to some extent. The idea that certain events are "too far away" or "don't concern us" was outmoded a hundred years ago, and the world has only gotten smaller since then. If you don't think that the strategic and political doings of the second-biggest player have a direct impact on our national security, then you are breathtakingly shortsighted. And let's not forget, our close allies in Europe get a big part of their energy from Russia -- piped through Ukraine. Wars have been fought for less. But I don't think that will happen in this case. Russia will keep the Crimea, that's a foregone conclusion. The only question now is whether they try to take the eastern provinces too, which have a lot of ethnic Russians.
