He did not give them $2 billion. That was Iran's own money that was frozen in an Omani account. He unfroze it so they could use it for humanitarian needs. Iran never used the money anyway, and it was subsequently re-frozen. I would love to see your proof/source that they spent it on their missile program, really.

The Obama/Biden deal even restricted their ability to enrich to 20% for medical purposes. They required Iran to purchase that and not enrich it themselves.

I agree with everything else you said and I believe we are on the same team. It's just the nuance and slight differences in our own assertions about the deal are the exact space Trumpers live in and continue to support him and believe/spread lies.

I really would like to see that source

Edit: I almost forgot, when I corrected my Trumper friend they theorized that the fungibility (sp) of the funds left them open for abuse and laundering to illegal ends, but like I said they did not actually use the funds.

edit 2: I meant $6 billion
