It is the first time that the sitting American president will visit the city where hundreds of thousands of people were killed by an A-bomb during the Second World War.

The objective sought by Obama through his junket to Hiroshima to be made before the end of his office is to leave his initiative to build a "world without nuclear weapons" as his political legacy and confirm the alliance favorable to Washington's implementation of the "Asia-Pacific rebalancing" strategy by attracting Japan.

Japan on its part seeks the aim of not missing this opportunity to evade its responsibility for redeeming its past by improving its image as a "war victim country" as it is always cold-shouldered by the international community for its inglorious past.

The above-said event cannot but be viewed as diplomacy of the U.S. and the Japanese authorities seeking different purposes, prompted by their mean political calculation.

Obama's trip to the A-bombed city would not help hide the true colors of the U.S. as a country of nuclear war maniacs and nuke proliferators as it has stepped up the modernization of its nuclear weapons under the spurious mask of building a "world without nuclear weapons."

Obama is seized with the wild ambition to dominate the world by dint of the U.S. nuclear edge only.

The U.S. in its "quadrennial defense strategy review report" mapped out in 2010 adopted it as a policy to ensure the unilateral edge of its nuclear force under the signboard of "nuclear disarmament" by underlining the need to maintain its nuclear arsenal till the goal of building a "world without nuclear weapons" is attained.

The U.S. has misled the public opinion by creating impression that the "nuclear threat" from the DPRK is the biggest problem facing the international community, far from reflecting on the worst nuclear crimes it committed by having threatened humankind with nuclear weapons for decades.

Wendy Sherman, former parliamentary undersecretary of the U.S. Department of State, asserted that Washington and Tokyo should make efforts to remain true to their commitment to ensuring peace despite nuclear threat from north Korea with Obama's Hiroshima visit as a momentum.

The U.S. is trumpeting about someone's "nuclear threat" and "a world without nuclear weapons" though it has desperately worked to throw the Korean peninsula and other parts of the world into shambles of a thermonuclear war any moment by modernizing its nuclear weapons and blackmailing others with those weapons. This is the height of hypocrisy and impudence.

What the survivors of the A-bomb disasters in Japan want to hear from Obama is nothing but the answer to the question as to whether he can completely eliminate the nuclear weapons in the world or not

Japan's ulterior design should never be overlooked.

Through Obama's visit to Hiroshima Japan seeks to put under carpet its true colors as a provocateur of the war and aggressor and go with impunity despite its past crimes by stirring up the "feelings of war victims" among its people and giving the international community a strong impression that it is a "war victim."

Such clumsy political calculation of the U.S. and Japan will only result in heightened vigilance of the international community.
