Germany did it to Czechoslovakia, Poland, Denmark, Holand, Begium,and France with a few Panzer Divisions. We don't have to do it all at once. We can carve off The Gulf islands, the ports, Khuzestan province and Kurdistan, for starters. And conventional resistance would look like the Desert Storm Highway of Death.

Yeah! we did this 35 years ago in 100 hours to a Soviet supplied, million man Iraqi army that the Islamic Republic of Iran couldn't put a dent in for the ten years Iran-Iraq War.
