Uh, no.
Totally. Vietnam was an unpopular war at home, as was Iraq (and still is), and we suffered far more causalities in the battlefield, but it still pales in comparison to the hit in global credibility with foreign nations that we have taken with Iraq and Afghanistan (p.s. thanks for pulling out, Canada). I mean, American at least had the audacity to frame the Vietnam war as a war against communism, which was evil, right?
Whereas we were seen as pretty much aggressors and bullies this time around, much moreso than with Vietnam. A lot of heinous stuff America did during Vietnam wasn't really revealed until after Vietnam.
No.
Obviously you have covered off that in terms of the mere human cost, Iraq and Afghanistan pale in comparison to Vietnam.
But even in geopolitical terms, Vietnam was worse. For one thing, Afghanistan was a necessary and proper response to the events of September 11th. (Initially. I'm not isolationist, but I'm increasingly of the persuasion that today its unwinnable and we should pull out.) Also, fuck you for the Canada jab.
So that's one for two. And yes, Iraq was a textbook case of a bullshit and unnecessary war of choice. Greatest strategic blunder of the past 30 years, strengthened Iran, weakened USA prestige and credibility, nobody's arguing that.
But still, Vietnam was worse. It owes its sole existence to possibly the most bullshit foreign policy theory in history. The Domino Theory. The US fights in Vietnam for a decade, at the cost of billions of dollars, thousands of lives, and LOSES, and......none of the negative consequences that were just about the sole purpose of fighting the war came to pass.
And you think Iraq and Afghanistan have damaged American credibility more than Vietnam? Vietnam was, essentially the
first war America ever lost. America went all in (or nearly so) in Vietnam for a decade, and LOST. Biggest superpower in the world embarrassed and bloodied by a third-world country.
In comparison, America is half-assing it in Iraq and Afghanistan (which may be a reason for why those wars have gone so poorly), and if America "loses" in these two wars, it ain't no big thing.
(aside: how many major powers supported the US in Vietnam? None other than a bunch of dinky-ass southeast asian countries. Iraq? Britain jumped all in. And don't forget Poland. Afghanistan? All major NATO powers have contributed troops, though obviously not all other than the USA, Britain and Canada are willing to put their troops in combat roles)
