Communist Hanoi and Taliban.

Who governs those countries matters, but America cannot spend unlimited blood and treasure ensuring that every country is governed by people we approve of.

The threats were eliminated. Mission accomplished.

Which is it, Taliban controls Afghanistan, or the threats were eliminated? Doesn't sound like mission accomplished to me. Americans can cope all they want, but those conflicts were utter failures.

The USA completely failed to eliminate the threat of a communist takeover of French Indochina.

Ask Pakistan if the threat of Afghanistan-based terrorism has been eliminated.
