The phrase "magical thinking" has often been used in reference to the left's economic policies. It seems to apply to their foreign policy as well:
1. Give Iran money.
2. ???
3. Iran deal worked!
The narrative Progs are trying sell is that Obama and LIEden had things working perfectly, and Trump F'ed it up. Of course, had Trump done nothing and Iran had lobbed a nuclear-tipped missile at Israel, which Iran may have been months away from doing, Progs would have blamed Trump for doing nothing
(while secretly rejoicing at whatever damage was done to Israel).
