Shares of several companies with ties to U.S. defense spending, including Lockheed Martin, climbed to new all-time highs on Wednesday, as tensions between North Korea, the U.S., and the United Nations continue to escalate.The growing conflict between the U.S. and North Korea sent many markets around the world down on Tuesday and Wednesday. One of the biggest reasons for the decline is a new heightened war of words between President Donald Trump and Pyongyang representatives, which stem from UN Security Council economic sanctions that were imposed unanimously on North Korea over the weekend—the sanctions will reportedly cut off $1 billion from the nation’s annual foreign revenue.Since then, an aggressive back and forth has occurred between the U.S. president and the North Korean capital. On Tuesday, President Trump warned North Korea against continuing its threats, or testing missiles, saying the U.S. would respond with “fire and fury like the world has never seen.”Pyongyang then responded that it would consider using missiles against Guam, a U.S. territory in the Pacific that houses U.S. military bases.Wasting little time, President Trump took to Twitter TWTR on Wednesday morning to boast about the renewed strength of America’s nuclear arsenal.My first order as President was to renovate and modernize our nuclear arsenal.
