The US threatened Niger by telling its leaders "to refrain from engaging with Iran and Russia in ways objectionable to Washington if Niger wanted to continue its security relationship with the United States".
The result? US troops expelled, Niger decided to end the "security relationship" on its own initiative
The US continues to behave like the mafia: Selling security and threatening those who are not interested. It does this everywhere, not only in Africa, but also in Europe. But times have changed, everyone (excepts EU's current leaders) can see that the US is declining rapidly.
