Your comment lacks not only paragraphs, but understanding of both US doctrine and understanding and US logistical systems. 1) Poorly trained (by highly motivated) Ukrainian soldiers are fighting successfully against the best the Russian Federation can offer, using both old Soviet era that they owned and manufactured (Most of the good Soviet gear was made in Ukraine), and old US and NATO gear. Old HIMARS, old M113, old Leopard tanks, etc etc. The best stuff being provided is Javelin, M777, a few Patriot batteries, etc. Even the Abrams and Bradleys are old versions. So the Russians aren't doing well, and are no threat in conventional terms. 2. The US wasn't surprised at all by the invasion, though the IC was surprised at how poorly the revamped Russian military performed. 3. The EU has been underinvesting in defense for 50 years, so their lack of deep inventories is no surprise. 4. This isn't WW2 where Detroit can switch in a month from building Studebakers to Sherman tanks. The only tank factory in the US is in Lima, OH, and has been building Abrams since 1980. The idea that defense items can be built quickly and cheaply ignores the complexity of the gear US forces use. 5. NATO members who have purchased the F-35 have the same capabilities as the USAF etc. There's no "export" version, and some purchasers are even part of the manufacturing process. And none of them have the F-22 as you imply, since it's not available for export (and the production line has been shut down for decades). 6. It's not "a big concern recently" about the tyranny of distance in fighting a war against China. This has been discussed for decades. 7. Finally, you say that the US has not fought a war against a near peer power in a long time. Well, duh. The US has had the most powerful economy since 1916, two oceans to keep enemies away, and hasn't had it's homeland significantly touched by an enemy since the War of 1812.
