The skepticism about the efficiency of the anti-DPRK sanctions is rapidly growing in the U.S. while the world attention is being focused on the Korean peninsula thanks to the DPRK's recent success in the test-fire of the SLBM, the commentary said.

This means the U.S. public declared the bankruptcy of the present Obama administration's policy of sanctions and pressure on the DPRK, the commentary noted, and continued:

The history of the DPRK-U.S. relations proves that sanctions and pressure can never settle the issue but results in complicating it.

The U.S. presidents from the 33rd President Truman in 1945 to the 44th President Obama have pursued the hostile policy towards the DPRK, the policy aimed at political destabilization, economic isolation and military pressure out of their inveterate repugnance towards it.

The U.S. harsh sanctions and pressure are serious criminal acts that deserve strong curse and condemnation as they seek to "bring down the social system" of the DPRK, a sovereign state, and infringe upon its sovereignty, dignity and vital rights.

It is foolish of the U.S. to recklessly work to bring down the DPRK, while perpetrating monstrous unethical crimes against it in disregard of international law.

The ever more reckless sanctions the U.S. and its followers slap against the DPRK would only compel it to further sharpen its nuclear treasured sword of justice and make the world clearly watch how the DPRK would tower after breaking the chains of sanctions, blockade and pressure.
