Wow, I think some members need a crash course in 20th century history...
If you think we have no dog in the fight, look up appeasement and Hitler. If you think global events have no bearing on US politics, European politics or our way of life, re-examine the cold war. For those of you who didn't hit puberty until the year 2000, ask your elders.
The US is not canada...we can't sit back and watch as significant nations handle worldly social and economic issues. Now more than ever, we have to be diligent considering the way of life we appreciate and the fact that we live in a global economy. We can't ride the coattails of another nation (like canada) or depend on the UN, the EU or NATO to take action. We can't allow this aggression to happen because it will ultimately erupt into a much bigger European conflict....probably led by the Germans, given their history of war, death and attempted genocide.
We are the major player in the world - and considering the blood lust and power mongering of Europe coupled with the failure of the EU economy - events like Crimea can only serve as a breeding ground for a major conflict. Imagine a Europe where there is an oil shortage, where the balance of trade is skewed...
The US must be involved or Europe will degrade into a war zone, ultimately dragging the US into their hate, war and pestilence. Given history, do you really want to trust Europe to handle this issue?
