Japan recently turned over to the United States enough weapons-grade nuclear material to make dozens of nuclear bombs. This was one of President Obama‘s few foreign policy “successes,” as part of his nuclear disarmament initiative. But his foreign policy successes may be more dangerous than his “failures.” Back in 2005, Sen. Barack Obama urged the Ukrainians to drastically reduce their conventional weapons, including anti-aircraft missiles and tons of ammunition. Ukraine had already rid itself of nuclear missiles, left over from the days when it had been part of the Soviet Union.

Would Vladimir Putin have sent Russian troops so boldly into Ukraine if the Ukrainians still had nuclear missiles? The nuclear disarming of Japan and Ukraine shows how easy it is to disarm peaceful nations — making them more vulnerable to those who are not peaceful.
