I don't think Japan's suddenly gonna do a 180 after being pacifist for 60 years. They're just worried about NK and other security threats, so they have changed the constitution a little bit. Don't get me wrong, it's unfortunate that they can't keep it the way it was but as a sovereign country you must keep your options open...
