The US is not going to fight a war over Ukraine and has ordered all its troops to leave Ukraine. Russia will invade Ukraine and leave it broken for even suggesting that it could join NATO and then leave. The US is only sending troops into Eastern Europe in case Russia stays and feels like causing trouble in bordering NATO countries where the US has Article 5 obligations.
The US military industrial complex is left wanting, Biden has sinking approval ratings and nordstream 2 is about to be turned on. All signs point to needing to start a conflict by the US.
