Many point to Vietnam, Iraq, Afghanistan, a natural instinct and there are indeed many parallels. The US track record is appalling (as I've written abt all of them). One key difference w/ Vietnam/Afgh at least: other presidents (even Trump 1.0!) decided not to attack Iran (and Iraq's regime). 1/
Can't get numb to this: The United States is stuck in a war it started, cannot end, and may further escalate to no avail, having dismantled its diplomatic apparatus, depleted its military stockpile, and destroyed its credibility. A historic strategic mistake harming millions in many different ways.
