Bill V, you're saying that America is to fight against political tyranny in other countries?
This train of thought leads to America writing checks that it can't cash in terms of support. Just look at what happened to Hungary.
I can see how the White House would want to support the Iranians who are against the dictator, but the language in this is not only kow-towing, but it implies a promise of support that we would be hard pressed to deliver.
If a rebellion over there ever did come to true fruition, like Hungary it would be quashed as while we promised support, we can't deliver it, short of an invasion of Iran, which no one will endorse.
To elaborate, if even a beloved and respected president like Eisenhower couldn't get America to back up a revolution that it supported then there is no way that Obama can.
