Oh come on, do not tell me you are still believing "bringing democracy" is a real thing in the USA  right? They do not do that, they never wanted to do that. Even if they had no intentions of doing anything or profiting in Afghanistan (what could you take from them, not like Iraq and oil) they still do wars because they need to spend that 700 billion on military somewhere otherwise why are they even spending so much?

What doesn't belong to them means that they will not stop until they have it, and yes you may not like that but it took them about 10 minutes to take those places, and weeks and yet not able to take Kyiv. Which is proof that Ukraine sort of cared about one, and not so much about the other.
