The idea that Ukraine is some kind of model of efficiency is just war propaganda. The Spring Offensive of 2023 was a trainwreck.
Oh, and Russia is better? Is that why they are stuck in Ukraine for two years now with the frontlines barely budging at the cost of something like 900,000 Russian casualties? The 2022 Kharkiv counter offensive liberated 200 km2 in just three months? The Black Sea fleet essentially nonexistent? Russia can't defend itself from deep drone incursions for a country supposedly more powerful? I don't know what your agenda is, but the results speak for itself. Like I said, it doesn't matter if the person wields a bigger stick if he can't use it well and keeps missing. The Ukrainian spring offensive failed in 2023 but the Ukrainians learned; the Russians didn't.
Similarly, the mythology of British/American logistical accumen is wildly overinflated.
They are better. The Allies have prepared for a war with Germany. The US alone have been able to mobilise its factories for war production and enlist 600,000 men (if I remember the figures correctly) in just six months after Pearl Harbor, unlike in WWI which took them a better part of one year to do so. The country already produced and sent hundreds of Liberty ships to supply UK and USSR. Germany, on the other hand, by admission of German generals after the war, stated they only had enough men and supplies to last them less than a year at the start of the war, if they don't defeat the West quickly. Because Hitler did not expect the Allies to declare war on him after invading Poland. Germany was actually on the brink of bankruptcy just before they invaded Poland.
On the Asia Pacific front, Japan also didn't inform Germany of the plan to bomb Pearl Harbor. Couple of days later, Germany declared war on US unnecessarily. So yes, tell me how efficient this is.
