The oh-so-sophisticated foreign-policy specialists and expert defense analysts are out in full force explaining to anybody who will listen that it would be a mistake for U.S. President Donald Trump to attack Iran.

A military assault on Tehran will not save the brave Iranian protesters from savage repression by the Basij and Islamic Revolutionary Guard Corps, say the “experts.” It won’t bring about regime change; it will only rally Iranians around the regime.

At best, it will bring to power an alternative Iranian dictator, a military general perhaps, who will be as repressive and aggressive as the ayatollahs. It will only dent and delay the Iranian nuclear-weapon and ballistic-missile programs.
