People like Ted Cruz act like destroying a bunch of stuff and killing a bunch of people means the US is winning the war.
War isn’t a sports game where the side with the most points wins. If the US fails to achieve its political objectives, which according to Ted Cruz is a new and friendly regime, then the US loses.
Anywhere US infantry concentrates near or in Iran, is going to get pulverized by Iranian missiles and drones.
The British couldn’t take Gallipoli in Turkey during World War I with 500,000 men. That campaign is analogous to potential ground invasions of Iran. For the US to invade, Iran’s missile and drone abilities have to be eliminated, but despite the many used and taken out, Iran seems to have enough left. In WWII, the US invasion of Normandy was a bloody affair, but Germany’s long range ability was taken out by then or on the eastern front. American military people may be in trouble if they land on Iran.
