1.The main reason land armies are no longer relevant to superpower conflicts is due to the nuclear peace. This is hopefully a long term situation but if the genie of normalizing nuclear weapons use comes out of the bottle, or if a method of using nukes that are "optimized" for manageable long term damage is developed, I can nearly guarantee you that large powers will again start having conflicts more often. If this happens, big armies will definitely become important again. Smart warfare, drones, guided weapons and all sorts of shiny systems for technologically sophisticated killing are fine as far as they go (especially for small localized police actions) but only large military forces and equipment ultimately allow any one major country to seriously fight another major country. 2. Also, as a quick note to the comment above yours, China is an economic and possibly to some extent resource threat to Russia, but the obvious target of simply overtaking a huge chunk of Russian territory through Siberia (which in purely conventional military terms I think China could easily pull off) wouldn't happen, because Russia despite all its modern systemic weaknesses, crumbling demographics and terrible military administration still has the single largest nuclear arsenal on Earth, which takes us back to point one above. 3. China is a strong power with a vast population that dwarfs that of the U.S and an economy that's getting very close to rivalling it in both sophistication and raw wealth production, but it's also strangely isolated in its power. The U.S on the other hand has strong affinities with much of western and central Europe, several other asian nations with large populations and also a much better relationship with the second most populous country on Earth, right next door to China. Russia would never readily take China's side in a global conflict even if it dislikes the western hegemony and all of these things combined along with others leave china in a state of extreme vulnerability if we were to start talking about a real, serious multinational conflict between it and the U.S. China's biggest strength is the economic dependence it has created in so much of the world, especially for manufacturing, but if a war were to break out between it and the west, this would in any case become a moot point, removing the one major incentive that any other country not directly next to it would have for trying to stay on China's good side. |
