The US military itself is a weapon - and that weapon is only as strong and effective as the will of the one wielding it. There was no will to "win" in Afghanistan, to a large extent because nobody had a clear understanding of what that even means. Hence the withdrawal, which is a political defeat. But militarily, you only need to look at the casualty rate to see who had the upper hand in fighting proper.

This reads like a troll farm/propaganda account. Nobody with a brain is buying what you are saying. With such a narrow look at the situation sure you can twist it to look like that. The US had no business in Afghanistan and it took them years to realize it. In that entire conflict the worst enemy was themselves. Compare suicide rates vs casualties in battle.

If the US wanted a total war they could have left that place a toxic wasteland with everything dead for thousands of miles. Instead it appeared to be some lame attempt to capture "hearts and minds" with a completely failed attempt at setting up democracy. Was it a total failure, yup. Was it a stunning military defeat? Nope. Just more M-I-L money burning. Money goes into one side, instruments of death coming out the other.

Wait... so the US army did poorly against guerilla combatants half way across the world, and therefore another country that lost in Afghanastan and a country that hasn't successfully invaded anyone that doesn't border them are a good match?
