the US will never give up its Japanese base.

it is the hub/springboard for all US operations in Asia (including Russia).

the US have a right to have thier bases in Japan, just as in Germany.
these are the risks assiosated with attempted global domination, a risk the warring party's would have been aware of at the time.

you cant gamble and then cry when you lose.

its a "secret" protocol because there really is no choice in the matter for the Japanese gov. however to apease local populations, to empower the J gov. and allow it to "save face" the USA makes it apear that the J gov. has some kind of input.

it has none.
the US base security will respond to any attempt to take the base by force, with force, and thus to do so would be akin to declaring open war with the US. (not a good idea at the best of times, even more so if you dont have an army)

thus force is out of the question.
leaving only the political option.
and as Japan does not carry any political wieght with the US (as this is primarily done by commiting troops to US wars - and even then.......)
the only hope for Japan would be China.

if china were to put on enough political pressure then the base could possibly be reduced with the nuclear arsenal removed.
however Japan and China don't get on all that well
(as Japan refuses to Apologise for WW2 war crimes [and were looking at stuff that made nazi death camps look like holiday camps, e.g. unit 731 , POW mistreatment and executions , imperial army bayonet training (on live chinese prisoners tied to stakes] )
Unfortunatluy for the Japanese PM it is not so simple,
in order to maintain popularity with the largly nationalistic voter base (and keep his job) he must be seen to save the national face, and defend national pride.
an apology would be an admission of guilt, an admision that the whole thing was one big f*ckup, something that would enrage senior voters (and OAP's have the highest %age of turnout when it comes to elections)
so even though the majority of "youth" in Japan would be able to accept an apology from the J PM, the proportion of those that actually vote would not.

thus it is a complex balancing act the Japanese PM must play.
China needs to be apeased, but too much and you lose power.
i would not want his job, thats for sure
