There’s a new sheriff in town.

Via NY Post:

Iranian military boats have quietly ended years of harassment of US Navy vessels in the Persian Gulf, and it looks like another welcome sign of a new cop on the beat.

For years, armed Iranian “fast boats” would charge at US ships in a dangerous game of chicken, rising to a level the Navy deemed “unsafe or unprofessional” at least twice a month. It was a clear signal of disrespect, and a test of what Washington would put up with.

But the game stopped last summer, the Wall Street Journal reports.

Officially, the Navy doesn’t know why. US Central Command chief Gen. Joseph Votel says, “I hope it’s because we have messaged our readiness . . . and that it isn’t tolerable or how professional militaries operate.”

But Tehran surely takes that “isn’t tolerable” message a lot more seriously now that President Barack Obama is out of office.

Obama, after all, had shown he wouldn’t enforce his own red lines, infamously blinking rather than live up to his own vow that use of chemical weapons by Syria’s bloody Bashar al-Assad would be a “game-changer.”
