Why would they give up over Iraq? It was part of Obama’s plan to get them more involved, ostensibly to help control the Iraqi Shia population. Iranians paid to plant thousands of IEDs that killed and maimed American troops for years, and Obama rewarded them with lifting of sanctions and a plane full of cash, among other favors.
Understood. Obama sold out Iraq, in favor of his more radical Islamic pals in Teheran.
