- Country with no strategic value to US. Nah, Iraq's got oil. (Vietnam had fish sauce, but US had no Pho shops in '62).
- Country mostly jungle and mountainous, providing cover for enemy movement. Nope, not much jungle in Iraq. Enemy seems to be able to move pretty easily anyway, though.
- US government claims general population welcomes military presence; check.
- Determined, indigenous enemy utilizing guerilla tactics; check.
- US forces rely upon heavy armor and aerial bombardment, creating resentment in local population; check.
- Enemy possesses source of supply and sanctuary in neighboring countries; check.
- US government delusionally claim signs of progress everywhere, doubters are called unpatriotic; check.
- Enemy is a coalition of nationalists and holders of a global triumphantalist ideology; check.
- US forces isolated from population by culture and language, dependent on local allies of dubious loyalty; check.
- Scenes of widespread violence and death on nightly news; check.
- Conventional wisdom is "no alternative to victory", elites are secretly pessimistic; check.
- American intervention universally deplored, even by close allies; check.
- Concern over deepening commitment causes US strategic shift to "localization"; check.
- Widespread suspicion of profiteering by companies with ties to administration; wait — did the Vietnam war have that?
Nah. The comparison's ridiculous.
