At the end of the day, in the long term, every war is determined by only a few things:
Number of citizens; more is better
Locally available resources
Production capacity
International support
On 1,3 and 4 the USA is far stronger than Russia and this will not change anytime soon, if ever.
What Russia has now is a weapon system that, using conventional means, can achieve effects similar to nuclear means. But note that Oreshnik is still experimental; They can't have many of these missiles yet as they are yet to be put into mass production.
Also, the Russian air force and navy are not on par with that of the USA. The Russian navy; we do not even have to talk about it. It is useless and always has been. Besides a few subs that carry the nuclear threat, there is not much to fear from the Russian navy.
The Russian air force has been developing (rebuilding rather). In Syria Russia showed it can perform sustained operations and keep up sortie numbers for reasonable lengths of time. However, in a direct confrontation with the US and NATO-allies, the Russian air force will not survive. Their newest jet is available in small numbers. In terms of strategic and tactical bombers, the numbers are very limited, as well.
However, and this is the thing, Oreshnik is capable of destroying airbases more or less by surprise. This is not a problem for the continental US, but it is for Germany, France and the UK. I have no numbers on Germany and France, but the UK only really has three airbases of note. Their main fighter, the Eurofighter is stationed at one of those bases. Numbers are fairly low as well, as many of the RAF Eurofighters are stationed abroad. Defacto, the RAF has 4 (!) Eurofighters for quick reaction to enemey airspace incursions.
