To be frank, it wouldn't be a surprise for Trump to claim "total obliteration" while having achieved nothing substantial.

This would also be a very convenient way to break the current impasse: Trump can claim victory and brag about US weapons, Iranians can continue their program virtually unscathed, perhaps after bombing some minor evacuated US base for show.

After the dust settles, Iran can withdraw fron NNPT and the next day have Pakistan ship them a bomb. Peace (via MAD) achieved! Maybe we should even give Donald his Nobel prize for that.
