Big big difference int odays world from the past. The threat in the post ware era through to the collapse was an ideological communist government in Russia /USSR as was with a strinng of satellite states and potential allias. China being one even if that was more ideological that.
Now they are now commies but still mange to get cast as the bad guys even though they have lost all their 'satellites/buffer states and cannot count on China as an ally. Russias still a big country but compared tot he US has a small population and the 65-75 M satellite populations are now all on the other side so its inate insecurity looms pretty large at the moment.
So they want to feel respected and rlevant so cyber warfare is on way of projecting power without risk of actual shooting war and playing around with destabilising western/NATO states being another. As they seem to have 'their man' in the White House ' and potentially aided the Brexit campaign as a way of driving a wedge between UK and Eu and therefor upsetting NATO. (the French have already put forward valid case that post Brexit they are the numero uno European military power and political influence.(also conveneint dry run for helping to get Trump in power)
Both these developments see Russia becoming strong and more relevant but not necessarily with any military objectives other than feeling they have ensured their own security through a weaken NATO.
In any case the Russians have already occupied most of the glitzy bits of London so why go to the trouble of a war
