2016, international situation is ups and downs: the United States presidential election is intensifying; across the Strait of Taiwan, The Democratic Progressive Party led by Cai Yingwen overwhelmed the Kuomintang, which has been in office for many years with an absolute superiority. The fourth nuclear test and satellite emission of DPRK (Democratic People’s Republic of Korea) completely pushed this country to the the cusp of international public opinion. Therefore, South Korea (SK) and the U.S. have repeatedly taken maneuvers and have frequently mobilized the stealth fighters, nuclear submarines etc. to have the containment and sanction on DPRK nuclear issues.

 

After the DPRK 's satellite launched, Park Geun-hy, President of SK, announced in February 10th to suspend the operation of Kaesong Industrial park in DPRK, and to forbid the foreign exchange to inflow to DPRK. South Korean Defense Ministry spokesman said on 22nd that SK will sign an agreement with the the U.S. about the operation of "THAAD" system deployment of the Joint Working Group in the morning of 23rd, but the date of agenda was confirmed yesterday that will be postponed to today or tomorrow. The relevant reports showed that the the fifth time containment and sanction maneuver, which is aimed at the extension of DPRK nuclear weapons of SK and the U.S. will also be held in California Fantengboge Air Force Base on Feb. 24th to 26th.

 

In the face of SK and the U.S.'s aggressive accusations and pressure, the North Korean leader Kim Jong Un does not change his attitude and continuously to adhere the road of economic construction and the nuclear armed construction simultaneously. And then, on the 22nd, Kim Jong Un inspected the Korean people's army forces military confrontation training and air and air defense combat pilots flight checking training.

 

Why the United States often exaggerate DPRK 's nuclear damage judgment? A close look shows that, this behavior is actually for striking at China. From the point of view of national interests, the development of nuclear weapons is a kind of upset to DPRK as a weaken country for self-defense. In the view of the United States, currently, China is the only one that has the potential ability to challenge the United States. In the view of the special relationship between DPRK and China, which can be said as if the lips are gone, the teeth will be cold, for firming its  position of the mistress of the world, the exaggerated accusations and measures of sanctions seeking about DPRK by the U.S. is carefully to arrange to intimidate and suppress China. While what measures the U.S. will take to use the intensified DPRK nuclear situation to strike at China, we can only wait and see.

 

For DPRK, nuclear weapons shielding task is also the priority work that should be done. Tungsten alloy has high density and strong nuclear radiation shielding capacity so that it can be a great material for making the nuclear weapons shielding of DPRK.
