I congratulate you Japaneses

and waiting for the carrier that you want to make, but I have a few asks :
1- Make the carrier yourself and don't ask help of USA military industries.
2- Ask your government to say to USA to remove its military units (bases) from Japan, because it is not good for you that a part of foreign army nests in your country and use your territory for their military purposes.
I think, if USA government leaves you alone, Japan will be deserve to recover and reinforce its defensive forces itself, although I don't see any opponent that threaten you among your neighbors. If America want to be friend of Japan, it will not be necessary they encamp in Japan. They can be a friend from remote!
3- Don't conflict and oppose with China in vain! It is a good country with a peaceful people and government. I myself like them and don't choose that you trouble them unreasonably. Behave to Chinese friendly and try to develop your political and trade relations with Beijing. This makes you more confident.
4- Don't interfere in the conflict that is between USA, South-Korea and North-Korea. As I told in a separate post, N-K is not considered as a danger for Japan. The people and government of N-K are concerned about their borders against USA and S-K that are confederates versus Pyongyang.
I heard recently, North-Kora tested its newest Balletic Missile and Kim Jong -un said that he will never use them versus anyone, except against those attackers that threaten N-K. I think it is a logical word and every country is concerned about the safety and security of its borders against occupants, especially N-K that is under siege of USA fleets in the seas, and in danger of ground attacks of South-Korea.
However, I recommend you Japanese don't interfere in the crisis that has been created in the area. I am sure, if USA army withdraw from waters close to N-K the crisis will be removed soon.
