people, who could very likely be affected by this stuff, e.g. Libya, what about what THEY want?
Americans have the luxury of ideology, not only is it quite likely that put to a choice many Americans would choose to strive for safety and assume that there are more than just binary choices in the matter, the rest of the world is involved in this too and that's a world emerging from a global financial crisis and maybe even beginning to address a 2-state solution in the ME, in an environment that includes strong actors that favor war on Iran.
Romney wasn't a mistake.
Though I agree with your principles, the difference between principle abstract value and reality is not insignificant and probabilities, no matter how strong we might assume they are in a certain direction, a direction that for some reason usually coincides with our own position on a given issue, btw, . . . that is, no matter how strong one thinks a given probability is, the reality is that you don't know whether the next instance of whatever will conform to your expectations or be something different.
Whatever the ideologues think about the principles, what about what the far far larger majority of non-ideologues want? Tell me why they don't count? Is it because we ideologues have somekind of superior position to decide what happens for them?
