You have no idea how geopolitics work. JCPOA matters more for the new administration than a couple of dozens F-35 for UAE. And the MIC as you call it is perfectly happy with hundreds of F-35 ordered by US alone. No big deal for Lockheed.
Wait, Pompeo believes he can take decisions binding his successor ? ROTFL.
It's approved by the State Department. US won't be able to go back to Iran Nuclear Deal even if Biden Wins. That jeopardizes the track to normalization of relations with UAE, Israel and others who are discussing including Saudi. The Senate with remain Republican and House too has bigger share of votes this time around.
You can forget about the Iran Nuclear Deal, not happening. Till the election is certified (far from it), Trump remains president. If a deal can be signed before 21st Jan, Biden can't undo it.
You're a bigger moron if you think LM and others will take this lying down.
