You are correct.
As they often say, Generals are fighting the last war.
Many folks hear “Russia” and they think we are up against the strength of the USSR. And even back then, the USSR was not as strong as we thought they were.
Are they pikers? No. Would we be able to take them on in a conventional war? Sure. Just our ability to project conventional weapons from off shore makes that a no brainer.
Of course, they are not Iraq and they are not rollovers. Even though they could take us into the deep innings, in the end we would win handily. Of course, nukes are a different issue. No one really wins there.
They also forget that our military alliance against Russia is a European military alliance called NATO, and is 28 nations strong and includes us, Germany, great Britain, France, Poland, and most of what used to be the nations of the Russian empire that Reagan brought down.
