I found this quote to be interesting:
"In our various games, discussions, and research we could not establish a clear link between Navy day-to-day forward presence and desired political outcomes."
When I was in 7th Fleet we did A LOT of presence missions, steaming all over SE Asia for 9mo/yr to conduct exercises (airshows) with allied nations, play some soccer with host navies, and maybe paint a school. Other than burning a lot of gas, airframe hours, and deferring a lot shipboard maintenance I'm not sure the end result was. I certainly doubt that anyone got anything but the most basic levels of training out of the exercises. Sure, we looked friendly with our regional partners but I'm not personally sure that making China feel all alone is the best strategy. Nations that feel encircled and alone aren't incentivized to play nice with others.
