Russian borders are still open (and anybody who actually doesn't want to participate can easily leave it) while Ukrainian borders are closed and they are going to mobilise even teenagers. Ukraine gets modern western arms (good for making selfies and videos in Tic-Toc), and Russia makes weapons to destroy those weapons cheaply and reliably.Russia is being bled dry. While they use out-dated Soviet equipment, Ukraine gets modern western arms.
You guys are really sucking us dry, its true, but you may be disappointed, its not blood.
