“Just like WW I until someone develops new tactics or new weapons systems, neither side is likely to advance much past their current positions”
That is what the F-35 Stealth Attack Aircraft is for.
Destroy all air defense. Then use the freight haulers like B-52 and B-1B.
that would require US force involvement, I know Biden is insane but surely, he would not give Ukraine access to F-35s, B-52s, and B-1B bombers, then again he is compromised.
