Of course he did. I think I’ve pointed out many of them in this thread or another. But I was speaking in terms of doctrine - specifically the US Tank Destroyer doctrine that was formulated in the panic of unpreparedness and the Fall of France in 1940 and misinterpreting the lessons of the rapid collapse due to German armor. This caused the US to keep the M-4 Sherman tank virtually unchanged until far too late in 1944, and it inhibited the development of bigger, better tanks such as the M-26 Pershing until the final push into Germany when its impact was more psychological than military. It could have been deployed by the late summer of 1944…

This site underscores the figures. Germany plus Italy/Rumania & Hungry etc are easily 50,000 tanks/SPGuns. Compared to Russia, they have a 2:1 advantage, while the west would be a little less since something like 20-25% of the allied forces were in the Pacific fighting the Japanese.
Just numbers. Firstly, how many did the Allies produce? Secondly, most Italian, Romanian, and Hungarian stuff was obsolete and on another, much lower level than the Allied equipment produced after 1941. The Italians were knocked out of the Axis by 1943 and at least some of their equipment was on the side of the Allies. And if you add up the numbers of German panzers actually not obsolete by 1942 (the Pz Mk IV, Panther, Tiger, King Tiger, and the last versions of the Pz Mk III IIRC) and even add the assault guns/tank destroyers such as the Stug and Jagdpanzer, and its a drop in the bucket against American production of the Sherman, various tank destroyers, and the Pershing. Then factor in the British and certainly the massive Soviet production of the T-34 and IS2s.
Even with the US and Commonwealth commitment to the Pacific, there were only so many tanks needed as Shermans were used mainly in an infantry support role as volcanic island geography generally did not favor tanks or battles of maneuver, and much of it was second rate until 1944…
Combined the allies have 4:1 advantage but if Germany can fight each allie seperately, they can defeat any invasion of “Europa”…that is if numbers alone were the deciding factor Especially if you consider production near the end. The combined allied production in 1944 was 51,000 tanks & SPguns, while Germany produced 19,000 tanks and SPGuns. Which suggests the allied advantage was disappearing. In this case the allied combined advantage is only 2.7:1 bearly enough to succeed. One can see why Stalin needed the second front so much and clearly even with this, more was needed. This is where allied Strategic Bombing campaign comes in, because the first thing they were able to achieve after neutralising the Luftwaffe, was to bomb the German fuel industry into extinction. Its kind of hard to wage mechanize warfare without any fuel.
How would the Germans fight each allied nation separately? Even if they only fought the Soviet Union bucked-up by US support, they might have achieved a stalemate, but complete unconditional Soviet surrender was probably highly unlikely. Secondly, play with numbers all you want, but the Luftwaffe was largely shot out of the air by 1944 and there was little fuel for extended operations. The Allies, especially the US, actually began paring down production by 1944, as well as her conscription manpower, because they already had more than they could move via the sea. And much more than they would need after the defeat of Germany…
You are also ignoring the cliche of the German Heer and SS being a steel tipped arrow on a shaft of wood. They were towing their Panthers by oxen in Normandy by early 1944 and came nowhere near the United States in production in trucks and soft-skinned field cars. All this while the Wehrmacht was still a rail-bound army using horses and ox-carts while the US and GB forces were almost totally mechanized. The Soviet Red Army was also still somewhat reliant on rail and horse, but significantly less so than the Heer. This thanks to the massive shipments of Jeeps and Dodge/Studebaker trucks from the US…
