I wasn't saying China should follow the USA in opening overseas bases (better to work on removing them from the region).
What I've been trying to say is that military spending is not something that exists in a vacuum; instead, it's arrived at by looking at the threats a country is facing. As an example: how many fifth-generation fighters should China acquire over the next 20 years? 25, 50, 100, 200, 400, 800, 1600, 3200, 6400 or 12800? I'd say the answer is between 1600 and 3200 (very broadly). Why would most people say anything below 800 is too low, when the number will be 0 for Vietnam and Myanmar, under 50 for S. Korea, 100 for Australia and so on? Why can't China be happy with 100 J-20s? Because the USA will be getting 2500 F-35s which will, along with a lot of other stuff, represent a serious threat to Chinese security. If these planes can be matched by a much smaller number of Chinese planes, that's great. If it can all be done with 2% of GDP, even better. If that's not possible, here's where a ramp up in spending comes in.
