The U.S wouldn't need ground forces. What we dont possess is the need to go to war with the only country destroying the deep state in Europe. Also, biden doesn't control the u.s military. Plus anyone who has had any strategic training in war planning k ows that geography is not a place to fight. The cold war was planned in the pentomic system which envisioned the use of battlefield tactical nukes. I spent years on the trace being trained and training soldiers to hold off the soviets invasion of Europe. Look up the Hayward doctrine and understand why our entire strategy would have been a failure. We only had 30 days sustained combat supply relying on merchant marine resupply within 20 days... until... we discovered a dual rail line from the far east Russia that would over whelm our ability to resupply moving soviet troops and equipment. Under Reagan, Admiral Lyons took a fleet off the west coast of the yakutz peninsula. First time since WWII. This let the soviets know we would invade there and forces the soviets to reconsider moving troops out of that area. There's lots more i could share but it would take too long. We would be fighting the wrong enemy if we attacked Russia.
