Japan is also mulling realizing the serial production of F-35 for their deployment for an actual war before long, after making its home-made Stealth known to the public.

It bluffs that its joint military exercises with the U.S. and the production and deployment of the Stealth fighters are of purely defensive nature to cope with "provocation" from someone in a bid to build up ill public opinion over the rocket test-launch by the DPRK for self-defence and China's advance into the sea.

Rodong Sinmun Wednesday says in a commentary this is a brazen-faced act that can be committed only by Japan which has inveterate bad habit of seeking its own interests by faulting others.

Holding the military drills under the pretext of "threat" from the DPRK, Japan is spurring the production of F-35. This is a reckless military act of the Samurai descendents aimed to realize at any cost the ambition for overseas expansion by taking the advantage of the U.S., the commentary notes, and goes on:

We have declared several times that if Japan takes hostile approach toward the DPRK by following the U.S., it can be target of the powerful strike means of the DPRK.

The DPRK does not make an empty talk.

If Japan tries to provoke the DPRK even a bit, defying its warning, we are ready to give vent to the pent-up grudge with the powerful military strike.
