That's probably an viable option last century (see: Philippines, Guam, Puerto Rico), but colonialism/imperialism is out of style right now so it would definitely not be easy to do that.
In practice, US foreign policy doesn't recognize international law and never really has.
The US could annex Afghanistan, and apart from the CCP doing a lot of complaining about it (primarily because they want access to Afghanistan's mineral wealth), nothing would happen.
