One thing is certain: if there is a war in the next few months, it is "come as you are." This is not WW II where we can produce the P-51 Mustang from drawing on a napkin to flying prototype in 102 days.
Besides the smallest Navy since WW I, a decimated Marine Corps, the Army only having a handful of Brigades combat ready, the Air Force smaller with an older fleet that at any time in history, the morale of the military is lower than it was post-Vietnam.
Morale is a massive factor in any fighting unit or army. Lord Nelson's fleet was outnumbered, but his men loved him, and he gave them better training. The British, with leadership, superior tactics, and fighting spirit destroyed the French and British fleets at Trafalgar 210 years ago this month.
The American military has been feminized, degraded, hamstrung, and smeared as a bunch of sexual harassers - all built on phony data and lies.
Critics try and compare military spending in Dollars between Russia, China, and the US. There are several fallacies to this argument.
One, we don't really know what Russia and China actually spend, we can only guess. Only the US is transparent with its actual Defense Spending.
Secondly, we compare apples to oranges. If a US factory produces a pair of boots that cost $150, a great deal of that cost was our way of doing business. Safety rules, union wages, legal costs, minority owned contracting privilege/profit by law, and on and on.
Russia and China don't play by those rules. They can produce the same or better pair of boots for $25 dollars.
On the battlefield, a bullet kills or maims the same, it does not discriminate about which costs more to produce.
