Within the next four years regardless of who is President China will not be able to overtake the US military. It very much will not be able to overtake the Japanese and US militaries with Australian backup. China has won in the ~10 year time frame at this point from what I can see, perhaps 20.
But should India mobilize things start to shift, much less Myanmar and the other nations in the area. For the time being yes, the "West" have the power to project to be a deterrent, but every day that goes by that deterrent weakens. That's why our relationship with India matters so much, and they wish to stay neutral so they can make money off both sides. A truth that I economically understand, but China is no friend to India, so their willingness to dance with the devil in this case confuses me.
I was rather shocked at China's... softening as soon as Trump was elected. But I don't think that's due to military strength, or regional influence. I think that's simply due to their attempt to maintain their 1 trillion dollar trade surplus which is greatly dependent on selling to the US and the EU. With both regions electing nationalist, and dare I say fascists into power... that dynamic changes. China itself is extremely fascist.
The places left that are actually free are dwindling.
