* Iran is a largely mountainous country.
* Iraq is a largely flat country.
* Iran has been a country since the early 1500’s, when the Safavids conquered Persia from the remnant Mongol regime and set up a government that has continued to rule Iran for the subsequent 500 years with occasional regime changes. That Iran claims to be heir to a 2500 year heritage of being a unified nation. Iran is a country that has a long and proud history of being a country for longer than the United States has existed, and has a culture and heritage older than Western civilization as a whole.
* Iraq was never a country until the British cobbled it together from three Ottomon provinces in the 1920’s and then fought a bloody war against rebels in those provinces to enforce their rule.
* Iran controls all of their territory as a unified nation, and its military is loyal to the Iranian nation.
* Iraq has never been a unified nation, and even under Saddam much of the nation and much of the military was under the rule of warlords who were paid off by the national government to stay loyal. The slick thing the U.S. did was pay them more than Saddam paid them, so that they (and the army units they controlled) stayed home when the US invaded. Obviously that cannot be done with Iran.
* Iraq’s military was based upon obsolete Soviet export gear that the Iraqi military barely knew how to operate, and operated via Soviet military doctrine which assumed the availability of unlimited amounts of men and equipment and the ability to retreat and wait for winter if facing defeat.
* Iran’s military uses a hodge-podge of American-derived (reverse-engineered), ex-Soviet, Chinese, and home-grown gear, and has home-grown military doctrines to go with it that have been actually tested against a Western army in Lebanon in 2006 and worked relatively well, in that the invading Israeli army’s tanks were swiftly disabled and the Israelis were forced to declare victory and go home, towing their disabled tanks behind them.
* Iraq had MANPADs which disallowed using helicopters for close support, but that didn’t matter because it’s flat so the US could use tanks.
* Iran has MANPADs wich disallow using helicopters for close support, but the US can’t substitute tanks there for close support because the land is so mountainous.
* Iraq’s air defense system was obsolete Soviet gear that they didn’t know how to use.
* Iran has the latest systems from Russia and China, which aren’t perfect but mean that we can’t just fly B-52’s over Iran and carpet-bomb them until a very lengthy (and expensive) process of degrading those air defenses take place.
Summary: Invading Iran would be much different from invading Iraq. Expect a constant stream of explosive devices, missiles, mines, and rockets to bring progress of U.S. tanks along tank-trap roads in mountainous territory to a crawl. Air superiority will be a given but it won’t be usable in the early days of the war, when Iranian air defenses would make things miserable for U.S. aircraft.
Now add in the fact that the Strait of Hormuz is overlooked by literally tens of thousands of Silkworm anti-ship missiles, all of which will render it impassable due to being littered with hulks within minutes of an invasion of Iran starting, and you will see why only a lunatic would start a war with Iran. Or Donald J. Trump. But I repeat myself.
What’s going to happen? Not war, hopefully. But when it comes to Trump, “*nobody* would be stupid enough to do *that*” doesn’t seem to work anymore for predicting what’s going to happen….
