Mr. Biden, Mr. Obama, Mr. Putin, and the assorted malcontents running about hunting rags and mismatched surplus NATO camo uniforms, where do you think this all leads?
Absolute worst case, Russia and the US/NATO get into a shooting war over Ukraine. Even if it doesn't go nuclear, you can bet it means the rubblisation of Ukraine and maybe a NATO and Russian base or two, a fracked global economy, and a whole lot of dead people.
If it goes hot, the useless idiots running around in Ukraine waving various flags and assault rifles will all be maimed or dead by Christmas. They have no idea what they're doing.
There's no win there. Just a long, ugly, deadly, fight.
