North Korea Unveils New Tactical Nuclear Warheads Amid US Presence in South Korea

North Korea's recent display of warheads designed for missiles to strike US allies in Asia and deliver a nuclear bomb to the American mainland indicates that Kim Jong Un has no intention of abandoning his atomic arsenal. The images published this week indicate Pyongyang has made progress in miniaturizing its warheads, which increases its ability to deliver a nuclear strike. North Korea's ability to deliver a nuclear strike has grown to the point that there are calls by some policy experts to declare the country a nuclear weapons state.
