President Donald Trump wants military commitments limited to those necessary to keep us safe and free. Whatever Trump may wish for, he has inherited a bad hand in South Korea. As a great nation, the United States must honor preexisting commitments to protect South Korea and Japan. Both are being levered by North Korea. The North Koreans are modern-day Vikings who use the threat of nuclear annihilation to collect blackmail without having to leave home. In the 1990s, President Bill Clinton foolishly gave North Korea $5 billion on the promise not to develop nuclear weapons. Instead, North Korea used that money to develop nuclear weapons.
