The recent United States missile strikes against Syria could increase pressure on North Korea to give up its nuclear weapons. Or the missile strikes could show North Korean officials the need for nuclear arms to keep the country safe from attack. The United States, France and Britain fired 105 missiles at three suspected chemical weapons factories in Syria early Saturday. The allies said they acted to answer a reported chemical weapons attack in the Syrian city of Douma. The attack killed at least 40 people and wounded or sickened hundreds of others. The Syrian government has repeatedly denied any use of chemical weapons. The raid on Syria comes as U.S. and North Korean officials are preparing for talks in late May or early June. They are working on plans for a meeting between U.S. President Donald Trump and North Korean leader Kim Jong Un. U.S. officials want the North to discuss plans for ending its nuclear activities. North Korea is expected to demand security guarantees from the U.S. government.
