US Nuclear Weapons attacked Jp

We were cheated and defeated completely by US 72 years ago. From the beginning since Edo period, over 100 years ago the strategy to settle and form US bases in all over Japan, how come this opinion?  The US Flag told everything shown on the external wall on Batlleship Missouri when we wrote down on the paper of Potsdam declaration acceptance surrender document signature.
The captain of Ancient Battleship squadron, Matthew Calbraith Perry invaded our Uraga in 1858 to force us open the trade with us!
But here, the US old Flag exactly the same as that time turning on the Mast tip of USS Susquehanna was shown on USS Missouri in Tokyo Bay on that day we approved defeat in 1945!
Is there any way to understand the fact in another way except my opinion mentioned above?
Japan was fallen into the trap and fit perfectly as expected by US, thanks to our Pearl Harbor Attack, US could participate in Europe Front and could defeat us with long lasting Asian Strategy since 1858 to arrange US Military Bases all over Japan Land.
Now, there exist 84 US Military Bases scattered all over Japan and they have also the permission to make use of 50 Japanese domestic airports.
Judging from this truth, even now the occupation by US is clearly lasting, more over, Japan Land is so to speak " USS Japan" that is unsinkable aircraft carrier.
As matter of sad, most of Japanese people do not distinguish our dangerous situation because we live in safe and peace daily lives.
More over, not a few people believe in that Peace has been lasting because of   US designed after the WW2 "The Constitute of Japan" in 1947 based on the concept of Peaceful, No War and No Fighting.
The reason why Japan Land had not been invaded till now by aggressive neighbor countries is that we have the peaceful constitute, not to fight, or there exist many US Military Bases all over Japan?
The answer is very clear to see what happened in Philippin after the US Military Force retired, immediately after that some violent country performed Military strategies around them and now much suffered from them.
On the other hand Russia and PRC want to our land recommending as some garden stones or fences for Military Strategies by the standing view of the same as US's idea.
We Japanese are leading pseudo peaceful lives in the extreme point where the strong magnets repel each other.
If we see peaceful blue sky, it is not because of calm sunny day in the flower garden but because we are now just in the middle center of Typhoon!
