WASHINGTON, Jan 29: Revelations from former national security adviser John Bolton’s upcoming book are adding some drama to the ongoing Senate impeachment trial of President Donald Trump. Some reasons they could be important:

WASHINGTON, Sept 11: John Bolton was in Mongolia. More than 1,200 miles away, President Donald Trump orchestrated an image for the world’s front pages by becoming the first U.S. president to set foot in North Korea, shaking hands with Kim Jong Un on the north side of the demilitarized zone.

WASHINGTON DC, Aug 23: National security advisor John Bolton declared that regime change in Iran is not a US objective. But he did promise to hit Tehran with sanctions and “other things.” So where does pressure end and regime change begin?
