I must say , this supposed strategy is completely delusional . Unfortunately , US has now come to a stage of "failing empire" . Failing empires tend to resolve their internal conflicts and problems by trying to look strong externally . US has its own set of problems (economics , demographics , culture , public morale ... ) Instead of trying to solve them , US is attempting to project power on international stage . Happened before , from Romans to modern times and always ended up badly .
What is a main point of this "strategy" : lets create more bases in more countries , so we could deploy our troops there so we could encircle China . Unfortunately , US forces are now spread everywhere in the world . US economy cannot sustain that so government is forced to withdraw them without "finishing the job" . We saw that in Iraq and now in Afghanistan and partially Pakistan - those who were allies of Americans are now fearing for their own lives .
Japan , Korea , Taiwan , Vietnam , Philippines ... should take note . What ever happens China will still be there , in their neighborhood . And some day , sooner or later , Americans would have to go .It is better for them to craft friendly ties with China while they still can , instead to be left at China's mercy when their protectors Americans are gone .
