I believe that the US intends to share our tech with Japan when we finish one.
While Asians in general are credited with having high IQs, one must regard the Japanese in almost another category. Their technology rivals/surpasses ours in many areas. Warfare is moving way beyond physical assets. If anyone can come up with an effective missle-defense system, it's the Japanese.
Once a system like that is deployed, aggressors are vulnerable to advanced offensive systems that rely on sophisticated technology that others can barely comprehend even if provided the blueprints (hint).
