Do they? From USA perspective, Russia is not a peer or near-peer competitor, USA only threat is China who is also the biggest beneficiary of this war. There are a lot of people in USA who believes that their support should be limited. Naturally decision makers also have to contend with public opinion and such sentiments will be unpopular (, may not want to raise public tension vis a vis China at this time etc) hence why some would choose to play into existing narratives that would shape popular support in the direction they seek.
Essentially, this is the game, the narratives are crafted to suit ones goals not the other way around. You have similar thing with climate change. The real question isn't whether it is happening, it is what we are going to do about it, it is multi billion (if not trillion) dollar question.
The common extremes is that the end is nigh and we need to go all in on green tech vs its fake/alarmism we don't need todo anything technology and private sector will sort it out as they always do. More importantly, one should understand that climate change is global problem, but green tech is not a viable or desirable solution for everyone, and thus someone will need to pick up the slack. Then there are super national considerations, and political realities.
For example, in Russia solar and wind energy are not as viable as they are in north Africa and north-west Europe respectively. Russia lack the infrastructure, even countries like Germany had issues, and Russia due to dilapidated state and its huge size would need to invest MUCH more with far LESS profit margins (wrose if you consider electric car charging stations). There are security considerations, many advanced schemes require cooperation and dependence on other countries, and one may not want the possibility of your industry grinding into halt with a flick of switch or hitting couple of main transmission lines. Finally, there are economic realities (Russia have a lot of cheap fissile fuels) and the global market.
Now ask yourself will Russian politicians who seek to stay in power, in age of social media populism/outrage and short attention span, try to educate their populace about the state of their country (which would have many negative effects to the economy ) or give ambiguous answers playing into existing narratives that gets them there..
