North Korea possesses an estimated 12-27 nuclear weapons and has threatened to use them against U.S. bases in South Korea. Within 1 mile of a nuclear blast, everything would be totally destroyed, while damage ranges from severe within 1.25 miles to light within 3.5 miles. The document speculates that North Korea's leader planned these threats due to lingering resentment from the Korean War and an animosity toward the United States and South Korea.
