Michael Ubaldi points out that the Japanese are seriously considering amending their Constitution to allow their military to take more over roles in military actions. The thing I find most interesting about this is that one of the stated reasons for the desired change is that it would allow Japan to take more direct action against those that attack the United States.
As Ubaldi points out, the Japanese seem to understand better than most that the United States is a target because we have been defending the world from tyrannic oppression for 50 years, often on our own. A growing portion of the people, both in and out of government, in Japan now seem to realize that they now have the capabilities to help us in that effort. The only real obstacles they have are the political will and constitutional obstructions. If they can summon the former they will also get rid of the latter.
I wish that the world was such a place that Japan didn't feel the need to take this action. But since there is so much danger in the world I'm glad that the Japanese people are willing to ask, "What do we need to do to help?" I don't know what will come of this, but the very fact that amending the constitution in this way is under consideration seems a sure sign that the world has changed.
