Why did the United States feel it was necessary for Japan to be rebuilt after World War II?

The United States saw Japan as a security state in hopes of containing the spread of Communism. Japan was already a regional (though damaged) power, and keeping Japan from falling under Communist rule was needed to keep the sphere of influence in Asia from swinging completely to Communism. Also, as a security state, the US can continue to post troops and security task forces to help defend allies in the area.

Later on, installation of radar for early detection, and missile bases for quick action/reaction set up was placed in Japan as a deterrent against Communist forces. Japan continues to be a key US ally after World War II in Asia, and will continue to be in the years to come.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
