I blame Bush mre than Obama. He promised the American people he would “never allow the worlds most dangerous regimes” to get nukes, then did nothing when they did. It’s also worth noting that all those intelligence agencies that now say the Russians “meddled” in our election without evidence said at the time that NK was 3-5 years from getting a nuke.
It's a twosome. Obama couldn't have made such a mess of things in eight years if GWB hadn't open the doors and got the ball rolling.
GWB seemed to be lazy when it came to future consequences of present events. JMHO
