Loose lips sink ships. Sometimes.
But this is actually good news. It suggests they pulled a thought-through Pentagon plan from a drawer, rather than Trump making things up on the fly. So hopefully, this is a strategy, not an idiotic and dangerous move like the one with Erdogan and the Kurds.
Risky but with a decent probability of success. Although failure is a possibility.
It also puts the boot on the other foot. Does Iran really want a war?
For once, I think this isn't Trump's impulsive dunderbrain in action.
