>>Now, on to Iran to finish the job.<<
Dream on, bro. The generals are not going to fight a two-front war while their rearguard is sitting in the middle of a bunch of Shi'ite militias with ties to Iran. Too bad we let THAT particular genie out of the bottle.
Who said fight a ground war?
Massive attacks to destroy production facilities, and let it fall into chaos.
At most, help the Kurd in the North.
