What China gets for all that money

You make a good point. Biden's been ridiculously weak with China, and Iran too.

But consider this: France had the strongest military in the world on the eve of World War 2. France did nothing while the Wehrmacht rolled over Poland, when western Germany was totally vulnerable, due to weak and cowardly leadership.

Then, when the Wehrmacht turned west, France fell so suddenly that it surprised even the Germans. Why did that happen? Still, there was poor leadership. But more generally, France suffered from extreme political division, which directly affected the country's defense. The French people were equally divided politically, of course. And the anti-war sentiments in France ran deep, along with other social issues.

Sound familiar?

Other people out there know how to set up a country - even the one with the world's strongest military - to lose a war.

yup... you project weakness and they will attack...

... and soon.

Yup... and you can bet they interfered in the last election to get dementia Joe installed...

Hasn't the US Air Force literally never lost a fight?

Okay, what if we have no fuel to fly? Wait, you mean fossils fuels win wars? Fossil fuels evacuate a region after a hurricane? Fossil fuels are still the life blood of the world, even China knows this to be true.

Never disregard the old until the new can replace it.

.... which is why the U.S. Air Force very much still uses kerosene. What on Earth was the point you thought you were making?

.....are you under the impression that the US military has been running on pixie dust? Someone's clearly told you that US fighter jets have been traded for Flintstones slingshot powered gliders these days but that's really really not the case.
