As North Korea's threat grows, ignoring it is not working

Quote: “The United States and its allies are in the worst situation yet in the long and unsuccessful attempt to curb North Korea’s quest for nuclear weapons and advanced missiles. Successive U.S. presidents tried isolation and sanctions, inducements and incentives. Nothing worked, and now North Korean leader Kim Jong Un is cozying up to a new benefactor, President Vladimir Putin of Russia. This is bad news for the multitude of U.S. and U.N. Security Council sanctions intended to restrict North Korea’s exports and imports, limit its financial dealings and root out its illicit cyber and crypto activities.”
