American interference or comment which appears to support either side would be disastrous I think. There is still hostility in Iran for what is perceived as American interference in the 70s. Some that are supportive of this potential revolution or ambivalent could turn against a side favored by the US.
While the students may be hoping for support from the US, that support would be disastrous for them. This regime is not limited by law. Their thinking is that they will do what they need to do to squash this uprising. If it becomes a symbol of rebellion against the US, then that makes any action against the students appear justified. The US needs to stay out of this...completely.
President Bush already HAS made comments.........multiple times...........in support of the Iranian freedom fighters within the country.
A comment now from President Obama supporting their desire for freedom would be VERY appropriate.....very American, in fact.
Of course, Obama will not do so for at least three reasons: 1. He is not an American 2. He supports the oppressors. 3. He is a coward.
