I have a feeling that the US wouldn't like it one bit. The US didn't like a secret visit by Abe's advisor Isao Iijima to Pyongyang, which apparently was news to the US.
After having been treated shabbily by President Obama on his trip to the US in April (or so Abe thinks) and his administration labeled "ultra-nationalists" who could harm the US interests in East Asia in the US Congressional report, Abe must have figured he has nothing further to lose in the eyes of his beloved US.
Abe blew it on his visit to the US, ditto on his visit to Russia, where Prime Minister Vladimir Putin got (or feigned) angry over the question by the Japanese press corp about the Kurile Islands and he refused to give Abe an assurance for selling natural gas to Japan.
Abe needs a friend, and Kim Jong-Un could be the one, I suppose.
Nikkei Shinbun (5/23/2013; part):
Speculation that Prime Minister Abe may visit North Korea, following the remarks of former South Korean ambassador to Japan
There is a speculation inside the administration and the political parties that Prime Minister Shinzo Abe may pay a surprise visit to North Korea. The speculation started with the interview of Kwon Chul-hyun, former South Korean ambassador to Japan, which appeared on the Chosun Ilbo, a South Korean newspaper, on May 23. Ambassador Kwon said, "It is highly likely that Prime Minister Abe will visit North Korea, between the end of May and beginning of June at the earliest."
Isao Iijima, Special Advisor to the Cabinet who just returned from North Korea said to the press on May 23, "There are various comments about resumption of negotiations (between the Japanese government and the North Korean government), but as far as I know, in fact, working level negotiations have been complete. It now all depends on the decision by Prime Minister and Chief Cabinet Secretary Yoshihide Suga." Mr. Suga didn't elaborate on the remark by former Ambassador Kwon, and only said, "I shouldn't comment, due to the nature of the issue. It is extremely important."
So, does that mean it is a done deal? Does Abe want to be like Kakuei Tanaka, who made a surprise visit to Communist China in 1972 and established a formal diplomatic relationship between China and Japan? Or does he just want to emulate Junichiro Koizumi, who visited North Korea to win the release of 5 abductees?
If Abe and his advisors think today's North Korea under the North Korean version of Boy-wonder dictator, shunned by every nation except China, is equivalent to Communist China in the 1970s, and the normalization of relationship will be hailed as a great diplomatic coup and success, they are literally insane.
As Zero Hedge's Tyler says about Abe and Kuroda:
We give up: raging schizophrenia and a sado-maso fetish is now a core prerequisite for anyone who wishes to follow the daily lies these central planning sociopaths spew with impunity.
