Even Mercedes-Benz

… has ceased all business operations in Russia. It appears that they were the last car company to make that move.

What? No more armored G-class tanks?

Mercedes farms that out to the aftermarket… Like this Canadian based firm

Or this Virginia US based company…

I think pretty soon the only foreign business entities doing business inside or with Russia will be arms dealers.

Russia makes its own arms…and sells them abroad.

Yes, but not enough for their current incursion into Ukraine.
They have been buying “kamikaze” drones from Iran for at least a few weeks, and they have placed orders with North Korea for artillery shells and… possibly… some type of rockets.
