Titular Peace Constitution

Japan will participate in the production of next fighter F35 following the relaxation of 3 principles of arms embargo after cabinet decision. We had been inhibited the rearmament after being defeated by US army 67 years ago? Do we do facing toward armament against Constitution of Japan hiding behind the word "Relaxation"? On the other hand, agree with I the opinion that some sophisticated armament, it but not too much would be surely deterrence of aggression. I'm worried it would happen being triggered by any trifle skirmish dispute.
