U.S. diplomacy will convince North Korea to curb its nuclear program and missile tests. As UN sanctions have failed to tame North Korea, and as the U.S. lacks a military option, President Trump should follow up with his campaign promise to meet with Kim Jong-un, writes Brahma Chellaney in The Globe and Mail. Engaging in "carrot-and-stick" diplomacy, Trump could use as leverage North Korea's interest in detaching itself from China to negotiate a peace treaty to end the Korean War, says Chellaney. Denuclearization as a main part of the treaty but not its sole purpose will give diplomacy a good chance at succeeding.
Diplomacy will not work to curtail North Korea's nuclear program. Economic sanctions and international diplomatic efforts have failed so far to deter the country's behavior or attitude about growing its nuclear capabilities. According to Helen Raleigh of The Federalist, North Korea sees its possession of nuclear weapons as the only way to be taken seriously, so there is no chance the country will rid itself of them, especially with China's continuous economic and political support. Therefore, she writes, the only option for the U.S. is to act defensively and deploy regional missile defense systems.
