Jim Geraghty of National Review and Greg Corombos of Radio America very warily approach the reports of North Korea supposedly being willing to scrap its nuclear program in exchange for security guarantees.  While fully aware that Kim Jong-Un may only be looking to bait us or stall for time, they are hopeful that the tougher approach from the Trump administration is starting to pay off.  They also wince as Al Qaeda leader Ayman al-Zawahiri emerges in a new video urging jihadists to stop fighting with each other and focus on a common enemy.  And they react with bemusement and concern as former Trump campaign official Sam Nunberg appears on several cable news shows to announce he is defying the subpoena from Special Counsel Robert Mueller, only to later admit he will probably cooperate.
