Instead what the US has shown over the last 30 years is strong conventional forces give soft power on a global level
The US soft power was "soft" not hard. Not its military but its cultural industries. Hollywood's stranglehold, for decades, upon the world's imagination was arguably more important than any weapon the US ever produced. That is real "soft power" where hearts and minds look to the US (to their system). Now things have changed. People want more foreign stories -- the world has just gone forward.
All their projection of hard power has been disastrous. Maybe there's an exception? It was their soft power, and that almost alone, which gave them large parts of their strength. That's also basically dead. It has no monopoly any more.
It is an economic competition more than a hard war you see being fought. Just listening to an economist (three hour conversation) hitting the nail on the head.
US will be 2nd soon (ten years? in both GDP and PPP) and India is now where I thought it was (showing that insane old Chinese growth every year, it will get larger: instead of 7% it'll be 17% in 20 years and then come down re China).
So you have a world where China, India, and US are the three largest economies by a relative mile. Then the EU and probably Russia and one or two others.
What can the Americans do? What they're doing imo. Forget the hostility toward Russia (it's happening however much you like or dislike it) and go for broke with something like the Bering Strait which re-centres the world's trade not just around the Rising Asiatic but also giving the US and Russia the key doorway to/through Eurasia and North/South America. If that replaces transit (shipping) which it easily can then you have an entirely new economy.
So the Americans are preparing for a peace with Russia and that makes a lot of sense. It's only the Europeans who are still deluded enough to assume that Russia will invade Europe and destroys its own economy in the process of maintaining these delusions.
USAID is soft power. Hollywood is softpower. A carrier group is not "soft power". It's the literal opposite. Centre for Democracy (or whatever the CIA calls it these days) is soft power. Etc.
What is more convenient if you are American? A proxy war against a nation which can safeguard your (and their) own relevance in geoolitical (economic) terms moving a century ahead or a war of attrition which many (if not most) assume was not as is preached by the ruling class choirs. See what the Americans do and forget the idea that it is just Trumpism.
Now, what's the best route for the EU. The African market probably. But cheap energy from the Russians in the meantime which requires a peace-deal. The cost of everything went through the roof because the Russians invaded, yes, but then we set sanctions against ourselves. "Don't fund the Russian war effort [let India and China do it instead, apparently -- cheap energy] and suffer the inevitable consequences of that stance". Being suffered to this day.
