The video game franchise "Fallout" is all I'm thinking when seeing news like this. In the Fallout universe, nuclear war breaks out in the year 2077 between USA and China (in this universe, the USSR still exists and is an ally to China) as the Earth's non-renewable resources like fossil fuels run out.
In our world, it just seems to be purely over who controls the World Order: the East or the West? I'm sure there are many factors I'm unaware of right now, but this buildup of military forces in the Pacific has me concerned for the future.
For more info on what I'm referring to, here's the Fallout Wiki's article on the "Great War" aka WWIII.
