Tensions on the Korean peninsula continue

On April 1 the Democratic People's Republic of Korea launched a short-range missile into its east sea just a few hours after leaders of the US, The Republic of Korea, and Japan pledged strengthened coordination to prevent the Democratic People's Republic of Korea from developing its nuclear and missile programs. 

On April 15 Pyongyang launched a Musudan missile capable of reaching Guam or Alaska. the Republic of Korea’s army said the Musudan missile launch failed but it was the first time the Democratic People's Republic of Korea had launched such a mobile ballistic missile.

Strengthening nuclear power

On April 24 the Democratic People's Republic of Korea said its ballistic missile test launched from a submarine under the command of leader Kim Jong-un had been a great success. 

Leader Kim praised officials, scientists, and technicians and asked them to speed up this project to increase nuclear power, which will enable attacks on American and Korean targets at anytime. 

Jeffrey Lewis of the Middleburry Institute of International Studies in California said if the launch is confirmed it is a big step in the Democratic People's Republic of Korea’s nuclear ambition. 

The US and Korean militaries spotted activities at the Democratic People's Republic of Korea’s Punggye-ri nuclear facility last week, sparking fears of more nuclear tests by Pyongyang in the future. 

Korea’s army has reportedly blocked roads in Kilju, north of Hamgyong province, where many military bases are located. The Democratic People's Republic of Korea also blocked roads before its 4th nuclear test early this year.

US President Barack Obama has warned of serious risks from the Democratic People's Republic of Korea’s continued weapon tests. He said although most of the tests failed the Democratic People's Republic of Korea gained experience and new knowledge and the US and its allies should be aware of that.

Confrontation instead of negotiation

The Democratic People's Republic of Korea’s Assistant Foreign Minister Ri Thae Song said North Korea does not intend to stop its nuclear tests even if the US halts its annual exercises with South Korea. Analysts, meanwhile, describe the Democratic People's Republic of Korea’s missile launches as part of leader Kim’s efforts to consolidate his image prior to the May congress of the Workers’ Party, an unprecedented event in 36 years. A number of analysts say leader Kim will use this occasion to declare his country’s possession of nuclear capability.

Faced with the Democratic People's Republic of Korea’s recent moves the Republic of Korea has maintained its alert level in fear of a possible 5th nuclear test. President Park Geun Hye has warned that if the Democratic People's Republic of Korea’s provocative acts continue it will face stronger sanctions and pressure. 

China has deployed military forces to its border with North Korea and the US is strengthening its defense capability. President Obama said Washington will deploy anti-missile systems and establish a shield to prevent low-level threats from Pyongyang. 

White House spokesperson Josh Earnest said the only way North Korea can integrate into the world community is to commit to a nuclear-free Korean peninsula and comply with its international duties.

The Republic of Korea, the US, and Japan have asked the UN to approve a new sanction resolution if the Democratic People's Republic of Korea conducts a 5th nuclear test. 

The resolution includes tougher sanctions like banning exports of crude oil to the Democratic People's Republic of Korea and banning Air Koryo flights to other countries. In Europe, France has urged the EU to approve additional sanctions.

The Korean peninsula has remained divided since World War 2 ended in 1945 and technically the two Koreas are in a state of war. the Democratic People's Republic of Korea’s recent missile launches have made peace prospects even more remote.
