Artillery is suited for combat with clear lines of confrontation. US doctrine actively tilts the battlefield so that these lines don't form, which plays to their strengths.
USA has a very advantageous geo position of oceans on two sides. So it's really hard for an enemy to show up with a ground army and continuous supply lines (like Russia). And US makes the military strategy to prevent that by all costs.
the US has arty and lots of it, but it leverages the absolutely massive airforce to do serious dropping of ordinance
both may take a backseat in the era of drones
Germany and North Korea are accessible by land to hostile powers, so their situation is very different.
A guy in a trench with a $25,000 electro-optical/thermal MANPAD can now snipe a $100+ million dollar 5th gen stealth fighter flying low and fast.
To decapitate a government you'd just need a roughly $500 drone you can make at home and some homemade explosives. Bonus points if you harden it from electronic attack and use INS and optical terrain recognition for navigation and image analysis for final targeting.

It's a weird time.
Russia is a nuclear power, I’m not sure if they’ve missed the moment or the fact so much was spent on its upkeep it was a magnet for corruption and all the rocket fuel has been replaced with pipe cleaner.
The thing that really annoys me is there’s lots of great Russian people, and Putin has herded them off of a cliff. Where does Russia go from here, or can Russia go?
A myriad of warlords? The Russian East disintegrates and China comes in to reclaim the land Russia took after the Boxer Rebellion 150 years ago?
