What is so worrying about China's massive military build up is that there's no benign explanation. China has long had enough conventional power to defend itself and more than enough nuclear weapons to hold up its side of MAD. It really just looks a lot like the king of China is preparing to start a war. It seems like in the best case he is preparing to take Taiwan and in the worst case he's planning to take all of As…
Both the UK and France have a completely independent nuclear response.
"What is so worrying about China's massive military build up is that there's no benign explanation. China has long had enough conventional power to defend itself and more than enough nuclear weapons to hold up its side of MAD."
Then there is even less explanation for the USA spending many times more on their military.
"It really just looks a lot like the king of China is preparing to start a war. It seems like in the best case he is preparing to take Taiwan and in the worst case he's planning to take all of Asia while perhaps his ally, the king of Russia, takes Europe."
None of these countries have kings.
"he simple fact is that if these two dictators can figure out how take out the U.S. then there's nothing stopping them from taking over the entire world. The giant has been sleeping since it declared victory in the cold war decades ago."
There is plenty to stop these. Russia is a waning power, with demographics working against it, and a regionally unimportant economy (smaller than Italy, which is also not going to take over the world). China, whilst growing fast, does not have the capability to project power and has a number of internal problems. This is all without mentioning it's rivals in the area, Japan, which is re-arming to a degree, and India, which is also well on the way to being a major economic and military power, if a few years behind.
