Russian economy is still tracking better than most of Europe even under sanctions. Im not saying the US, but the whole of Europe is a mess right now, take away the sanctions and Russia would be outperforming them on growth.
Russias timeframe to win in Ukraine's only stifled by the west, or basically US weaponry and intelligence, some help from Europe but I think we can all agree Russia is no match for the US,discounting nuclear, but Europe without the US and UK would be a different story. Anyone who hasn't watched in amazement of the modern warfare weaponry against Russias more traditional approach, put it this way, the US can be stoned gay trans feminist, whatever floats the USA weird boat, but they have the technology and weaponry to support their global agenda.
This conflict isn't Vietnam or a proxy war with China, its the US in a proxy war with Russia, The Chinese would be thinking twice about fighting a proxy war in Taiwan.
I still respects Putins right to defend himself from further NATO expansion.
