One can do two things at once. In fact, I would accuse military leadership of being derelict in their duties if they didn't have backup plans for their backup plans.

It also boosts negotiation power. Carrot/stick, etc.

One can do two things at once.

One is clearly not doing it though.

Seriously derelict for thinking assassinating Ayatolah, and/or girls school, for surprise "benefit" was going to win. Rushing a backup plan that took 2 weeks to get there, is the best kind of evil: a stupid collapsing evil.

All we can do is hope for regime change (In the U.S.)

Except the US in the last round of negotiations for example showed they weren't seriously negotiating but distracting while planning so no reason to trust them.
