“Why do you guys keep posting that when you know that Russia shares about 1600 miles of border with our alliance nations and forces, and never seems very concerned about it?”
Those countries are not as close to the Russian heartland as Ukraine. I don’t blame the Russians for being touchy about foreign troops there. The Germans launched three offensives into Russia from Ukraine; the southern prong of Operation Typhoon, Case Blue, and the southern prong of Operation Citadel.
Which doesn’t explain why they keep posting that ignorant claim over and over, year after year.
