The Iraq and Afghanistan wars ended with the US famously achieving few to none of its long-term war goals and a huge public and international sentiment against further regime change adventures. If those resisting the US occupation had given up earlier, would the US neocon warmongers have been so thoroughly driven from power? Or would they have been emboldened by the victory and more likely to continue with their promised invasion of Iran? Russia is a nuclear state, and will in no rational scenario ever "come under attack by the entire world" due to the inevitable consequences. On the other hand, manufacturing casus belli again and invading Ukraine in a few years is an obvious outcome.
