While I doubt that we are heading toward a international crisis in the Ukraine, it is not impossible. Paul Craig Roberts has written an interesting article on this. He points out that the Ukrainian protestors are funded by the West to destabilize the Ukraine:
In an eight minute, 46 second speech at the National Press Club sponsored by the US-Ukraine Foundation, Chevron, and Ukraine-in-Washington Lobby Group, Nuland boasted that Washington has spent $5 billion to foment agitation to bring Ukraine into the EU. Once captured by the EU, Ukraine will be “helped” by the West acting through the IMF. Nuland, of course, presented the IMF as Ukraine’s rescuer, not as the iron hand of the West that will squeeze all life out of Ukraine’s struggling economy.
The article is well worth a look.
