You want me to answer the question that is your last paragraph?
I have no idea! I don't live in Russia, I'm not well-versed in modern warfare and military technology, I haven't studied diplomacy, I have no idea how Russia would respond if nato suddenly brings to bear every piece of military hardware it can muster.
Literally all I'm saying is that more expensive doesn't always mean better quality. That's literally it
This is the part I think you haven't shown, even a little bit. First you linked a wikipedia page which was a list of countries with the highest military expenditures, then you linked wikipedia pages for a bunch of american military hardware. At no point did you try to compare american military hardware with Russian military hardware, either in quantity or quality. The only comparison you've made is in terms of expense.
