Not really, the USSR had a very large amount of manpower the US and NATO could not fight reasonably right after the war. France and UK were nearly baren of troops. The US was still hurting, and would have had to keep sending troops over.
You forget that by 1945, the USSR had a very large stake of puppet states.
Also, by 1945 most equipment the USSR had was their own made, and were not really using US stuff anymore
All soldiers from puppet states would wait to surrender.
About soviet stuff - tanks were very good, but needed fuel.Bomb refinereies, and they would be useless.And all new made would be without american radios.How far they would come,when messages need dude with babber on top of commander tank ?
Guns were good, too - but need american train to deliver ammo,american trucks to change position,and becouse few crews were good trained, must fire keep wheel by wheel.
infrantry need american troops to relocate.
What USA could do ?
1.Bomb Ploesti and Baku - no fuel for soviets.
2.retreat from one german river to another, bombing soviet forces in process.
3.Target especially trains and trucks.
4.Send Marines to Kołyma - soviets had real death camps there, np road to deliver help,and only NKWD thugs to terrorize prisoners.Only by sea you could get there - and soviet navy was always shitty.Show pictures in press,so people would knew who they fight.
When after 6 months soviets finally get to Ren ,and soviets was out of fuel,send fleet to Baltic.During WW2 6 german cruisers bombed soviet forces whenever they wonted- what USA battlewagons could do?
People in Poland and Baltic states waited for help - and would welcome anybody as saviour.
Cut off soviet forces in Germany, built airfields in Poland, and send B.29 over soviet cities.Non soviet fighter could intercept them.
If Stalin do not surrender,send soviet soldiers who surrender against him.If 700.000 soviets fought for German AFTER they murdered 2 millions of soviet prisoners,how many would fight for USA ?
