They invade, bomb and kill people for no reason other than to install their own puppet government. Its annexing by a different name. Afghanistan was in annexation for 20 years, the sham eventually came to an end. Wordsmith doesn't change what happened.
The United States doesn't really care about free elections, heck ask Italy.
Once the Taliban took over in Afghanistan the United States froze all the central bank assets, why? Well, the puppet regime put into place by the United States fell, but the United States had already signed an agreement to assist in rebuilding Afghanistan.

The United States clearly has taken over those oilfields in Syria, exactly what do you call that? Its just words. Annex, taken over, captured, stole, etc. Does it really matter?
