WASHINGTON—President Barack Obama slapped North Korea with more stringent sanctions Thursday for defying the world and pushing forward with its nuclear weapons program, weeks after it launched a satellite-carrying rocket into space and conducted its fourth underground nuclear test.
Both actions led to worldwide condemnation of the reclusive country and fueled fears that it continues to move toward building an atomic arsenal.
Democratic and Republican lawmakers, many of whom argue Obama hasn't been tough enough with North Korea.
