I have yet to hear what possible good it would do for the President of the United States to encourage the protesters, except to give the Iranian regime a better excuse for killing more of them. McCain’s bleatings are either for domestic political consumption or self-satisfaction, a form of hip-shooting onanism that demonstrates why he would have been a foreign policy disaster had he been elected.
To put it as simply as possible, McCain—and his cohorts—are trying to score political points against the President in the midst of an international crisis. It is the sort of behavior that Republicans routinely call “unpatriotic” when Democrats are doing it. I would never question John McCain’s patriotism, no matter how misguided his sense of the country’s best interests sometimes seems. His behavior has nothing to do with love of country; it has everything to do with love of self.
