North Korea: Are US provocations making things better or worse?

As North Korea continues its nuclear program, the Trump Administration says it's lost its "strategic patience." What does that mean? A US carrier and a nuclear submarine are conducting drills in the Western Pacific, and China is urging President Trump to exercise "restraint." The entire US Senate was bussed from Capitol Hill to the White House. Was it political theater or did they learn anything new? We hear about possible options from diplomacy to economic sanctions to preventative war.
