> As I said elsewhere: In the last few years the US has been run out of Iraq by Iran, Syria by Russia and Afghanistan by the Taliban. I don't see much appetite for going back to any of those.
As was said elsewhere here, the Afghanistan war was won quickly. Afghanistan was also easily kept. And that's fighting against an opponent using guerilla tactics. What failed was nation-building. But that's not the goal with a confrontation with China. The goal is symmetric warfare to hold back an invasion. Defensive warfare is easier than offensive, so the cost would be far higher on China invading than Taiwan/US defending.
