The Pacific is the "priority" theater?

I find this twitter post interesting. I've heard of China being our "pacing threat", but never that the Pacific is the "priority theater". The verbage about our tilt to China is the new rage in the Pentagon but I have yet to see any action to follow thru (sorry but the Marine Corps Force Design 2030, even if conducted in the most optimistic way, will only be a sad and probably sorry side show). Are we seeing the new "hotness" without substance in the Pentagon?
