No ... it is my position that we need to take a very public and clearly stated posture supporting the duly elected government in ANY country, but certainly in the Ukraine. That support may, and we must be willing, include money, materiel, and, as a last resort, manpower. Economic sanctions against a few (not even ALL) of Putin's friends is a joke. Power must be met with power - and the perception of power must be met with a corresponding perception of power. My recommended actions in the Ukraine have been clearly spelled out here and in other threads.
We have - pardon the expression - waffled on our support to the Ukraine, the Syrian rebels, the Libyan insurgents, and the Egyptian peace movement. We had the opportunity, by actively supporting Arab Spring, to dynamically change the course of history in the MidEast - instead, we dithered, we lied, and we backed out. The ensuing vacuum gave rise to the Muslim fundamentalists.
We quit on our allies in Iraq and Afghanistan. We showed ourselves to be a country with no courage, no honor, and no backbone.
