the nation that has threatened world security in recent years because of its interest in becoming a nuclear power is : North Korea
Though it's really hard to find any information about the country since their president heavily censored the flow of information, we managed to find a few video footage of them testing several of their weapons.
Answer: North Korea
North Korea (Democratic People's Republic of Korea, DPRK) is a country in East Asia. It is considered a socialist state, in which the means of production are owned by the state and most services are state-funded. The North Korea government has also been accused of human rights violations by international organizations.
North Korea is no longer a party to the Treaty on the Non-Proliferation of Nuclear Weapons. The country has a military nuclear weapons program and also chemical and biological weapons. This has caused concern all over the world, as it places a significant threat to world security.
