Thats rather simple to understand, for somebody coming from eastern Europe. russian mentality permeated entire region during their enslavement of what is now eastern EU bloc for +-40 years, to have a battleground for nuclear war with west that never came. It happens when all your politics is orchestrated in moscow and you have almost a million soldiers deployed in bases all over the place for decades, with nuclear weapons and all that.

See, russians have massive inferiority complex. Against everybody, but mostly the more successful ones, meaning west in many aspects. Their approach to, well, everything is vastly ineffective, corruption, nepotism and similar stuff grinds any attempt at progress to almost halt. Just go there and see for yourself, they have money literally sticking out of ground left and right yet outside moscow and st petersburg you are in central Africa in terms of development.

All this, propagated to 21st century where everybody seems to go ahead of them. A lot of frustration, envy and schadenfreude. A (correct) feeling russia is left behind and becoming insignificant local force at best, and laughing stock of whole world more realistically. Plus, human life is generally almost worthless there, its mafia state pyramid to the core.

With all that, its vastly easier to keep reinventing enemies that are always guilty at damaging poor old russia, rather than cleaning up that clusterfuck and actually owning the shit they created for themselves. Its enough for general population. There is not much more actual stuff to the question 'why west', rest is just PR for simpler folks. A dictator never wants smart, strong and free population, double that for russia. Downtrodden, hopeless desperate folks are much easier to manage and manipulate.
