Three times the size of Iraq and twice the population.
TEN times the size of North Vietnam and four times the population.
Twice the size and population of Afghanistan.
We aren't launching a conventional invasion of Iran. Trump is stupid but he isn't THAT stupid. This administration does like social media wins, though. My guess is that we'll probably launch a token special forces "raid" of a soft target in Iran, stick around long enough to get pictures to post on X and Truth social, and that will be it for the publicly visible ground component.
I also think we'll experience blowback from this fiasco years down the road through terrorist attacks by Iranian proxies and lone-wolves. The Iranians don't forget.
