> What happened to Vietnam and Afghanistan?

My understanding of Vietnam is that the US was defeated politically, not militarily. Afghanistan poses even less of a military threat than Vietnam.

And yet we're the ones walking away.

not just walking, negotiating with the Taliban ( what happened to "we don't negotitate with terrorists" )

We spend A LOT of lives and A LOT of money. And had nothing to show for it.

Civilians lost (their lives). Soldiers on both lost (their lives). The MIC won.

That sounds like defeat to me.
