Why is the United States so quiet on the Jasmine Revolutions?

Well, the so-called Jasmine Revolutions are still rolling through the Middle East, and are lapping at the shores of Asia. Tunisia and Egypt have thrown off their decades-long dictators, and countries like Bahrain and Libya are struggling to do the same. Even Iran and Yemen are seeing mass demonstrations against tyranny. And yet, the United States has remained relatively silent. We have engaged the conflicts only after the victors are clear or the attacks on demonstrators are so monstrous that they can not be ignored. How is it that the country that regards Freedom and Liberty more highly than any other, has so little to say?

My best guess is that or leaders - primarily President Obama - is thinking one of these thoughts:
1. We're hated in the Middle East, so our support may hurt more than it helps.
2. We've supported too many Middle East Tyrants to credibly support democracy.
3. We can't afford to send money or troops, so we won't support with words.
4. These revolutions have nothing to do with America.

Unfortunately, all of these thoughts are incredibly cynical. Especially when we're lead by a man who campaigned on "Hope" and "Change". Hope and Change are coming to the Middle East. I'd rather we go down in history as standing with them, than standing on the sidelines.
