Containment of Japan
There have always been talks about the containment of Communism and China as if this is something only the Empire and its allies can do. Why don’t the Russians and Chinese do the same and starting with the containment of Japan? Russia, China, Taiwan, Honkong and Korea, all have problems with Japan and were victims of Japanese aggression in the past.
The above countries are not dependent on Japan anymore and can do away with trades with Japan. All they need is to cut down on their trading activities with the Japanese, boycott or sanction Japanese goods etc to strangle the Japanese to go on their knees.
Crippling of the Japanese economy will force the Americans to extend its helping hands, but being a bankrupt country there is really nothing the Americans can offer except its military might. Neither can Europe be of any help. If there is anything that the East Asian countries want to do against Japan, this is the moment.
The combined forces of China and Russia, plus Korea and Taiwan would be something to keep the Americans wary and not to do anything foolish.
Hey, the containment game can be play by other parties too.
