Just over two years later on March 16, 2012, North Korea announced it would launch its Kwangmyŏngsŏng-3 satellite to mark the 100th anniversary of the late Kim Il-sung's birthday. This announcement triggered American anxiety as satellite launches are technologically contiguous with missile launches. This tampered with Kim Jong-un's earlier optimistic overtures and generated speculation on the issues confronting the new and young leader back in North Korea. The United States also suspended food aid to North Korea in retaliation for the missile plans.

Daniel Russel, Special Assistant to the President and Senior Director of Asia, and Sydney Seiler flew to Pyongyang from Guam in August 2012 and stayed there for two days. A South Korean diplomatic source said "apparently President Barack Obama, who was then bidding for a second term in office, secretly sent the officials to North Korea to minimize disruptions to the U.S. presidential election." Other analysts say, "Nobody can rule out that such direct dialogue between Washington and Pyongyang will continue in the future."

However, on December 11, 2012, North Korea successfully launched a missile in contrast to its failure in March. The United States strongly condemned the action as it is widely believed that North Korea are developing long range ballistic missiles that would reach the west coast of the US.

On March 29, 2013, Kim Jong-un threatened the United States by "declaring that rockets were ready to be fired at American bases in the Pacific." The declaration was in response to two B2 stealth bombers that flew over the Korean peninsula on the day before. After Jong-un's declaration, the Pentagon called for an advanced missile defense system to the western Pacific on April 3. United States Secretary of Defense, Chuck Hagel, said that North Korea posed "a real and clear danger" to not only the United States, but Japan and South Korea as well. The deployment of the battery to the US territory of Guam is the biggest demonstration yet that Washington regards the confrontation with North Korea as more worrying than similar crises of the past few years. It also suggested they are preparing for long standoff. While visiting Seoul, South Korea on April 12, 2013, United States Secretary of State, John Kerry, said "North Korea will not be accepted as a nuclear power", and that a missile launch by North Korea would be a "huge mistake". On April 18, 2013, North Korea issued conditions for which any talks would take place with Washington D.C. or Seoul. They included lifting United Nations sanctions and an end to United States-South Korean Military exercises.
On April 26, 2013, North Korea said it had arrested a U.S. citizen for committing an unspecified crime against the country. U.S. officials said that person was Kenneth Bae. On May 2, 2013, Bae was convicted of "hostile acts" and sentenced to 15 years of hard labor. The U.S. has called for his release but North Korea has rejected any possibility of allowing prominent Americans to visit the country to request his release. Dennis Rodman, who had previously visited North Korea and become friends with Kim Jong-un, tweeted a plea for Bae's release. Rodman has since said he will visit North Korea again in August and attempt to free Bae. On May 2, 2014, Pyongyang's Korean Central News Agency (KCNA) released an article composed of four essays written by North Korean citizens. The content of the article carried heavy criticism and racist remarks towards U.S. President Barack Obama.

Two American citizens were detained in North Korea in June 2014, accused of "hostile acts". On July 28, 2014, the United States House of Representatives voted to pass the North Korea Sanctions Enforcement Act of 2013 (H.R. 1771; 113th Congress), but it was never passed by the Senate. On August 20, 2014, during annual U.S.-South Korea military drills, a spokesman for the North Korean government referred to U.S. Secretary of State John Kerry as a "wolf donning the mask of sheep", the latest in an exchange of taunts between U.S., South Korean and North Korean government officials. In January 2015, U.S. President Barack Obama indicated that he believed that over time the North Korean government will collapse. On July 28, 2016, a North Korean top diplomat for U.S. affairs claimed that the United States crossed the "red line" for putting leader Kim Jong-un on its list of sanctioned individuals, which was perceived by officials as the United States declaring war.
