The Trump administration is under pressure to pull out of a landmark nuclear arms pact with Russia. Some worry the INF Treaty is the only thing standing in the way of a full-blown arms race.
President Trump has made a big deal since his election about his new relationship with Chinese President Xi Jinping, insisting Beijing is "working very hard" to pressure North Korea since the two leaders' meetings at Mar-a-Lago earlier in the year. Mr. Trump seems to be combining China's newfound sympathy to the U.S. position with a "big stick" — three U.S. aircraft carrier battle groups, which rotate off the North Korean coast.
Time to think the unthinkable.
