But your own solution brings up the very same problem. You talk about the bombing of Serbia as something that caused this. But the alternative is to not intervene in Serbia because we recognize a Russian sphere of influence there. That is entirely the root of the problem. Russia wants a sphere of influence in Eastern Europe and that is not acceptable to any of the countries there or NATO allies in Western Europe. The only ways to ally with Russia and Western Europe simultaneously are to either get Western Europe to agree to a Russian sphere to their east (impossible after the USSR fell), or to get Russia to accept that it is no longer a great power and rather simply the equal of France or Germany and therefore not entitled to its sphere of influence as the US is. None of the things you bring up address this fundamental conflict.
