With the right equipment and intelligence AND dry ground, the ukes should slice through the rus lines like the US sliced through Saddam Hussein’s lines in Kuwait in 1991.
The attack has been over hyped to a point that anything but a victory will be seen as a defeat. I believe it is being set up to pull in NATO-USA into the conflict. In Iraq the USA dominated the air—The Ukraine doesn’t have control of the sky. Each day Russians get better at war fighting and dig in deeper. We shall see what happens BUT If I was Mr. Z I would think of a way to get direct US help because without it he’s doomed.
