Why Did North Korea Develop Nuclear Weapons?

Scott Horton gives a very brief history of what happened (57m38s):

It was all George [W.] Bush's fault. [He] probably deliberately provoked them into doing that.

First, [the US] abnegated the Agreed Framework deal, then they announced a whole new round of sanctions, then they announced the Proliferation Security Initiative which said that we can seize all your boats on the high seas and do whatever we want with them [...] and then they announced the Nuclear Posture Review that said we just might attack you with nuclear weapons.

And only then did the North Koreans withdraw from their end of the Agreed Framework, announce they were withdrawing from the Non-Proliferation Treaty like in the deal it says you have to announce 6 months beforehand, and only then did they withdraw from the treaty, kick the IAEA out and start making nukes.

And i guess the thinking [in DC] - if you can call it thinking - was, don't worry, we'll be done in Baghdad and we’ll be ready to go to Pyongyang before they get their first nuke together, except that Oops instead we just essentially handed them an arsenal of nuclear weapons when they were perfectly happy within the Non-Proliferation Treaty as a threshold state under the Agreed Framework deal which America had never even lived up to our side of.

It just took Bush repudiating it and threatening them with an H-bomb first strike to make them withdraw from their end.

28 Obama Foreign Policy Horrors (and three genuine achievements)

With Donald Trump in the White House it makes sense to worry about the direction US foreign policy is going in. But such understandable concerns about the future may lead us to forget just how destructive the previous president’s foreign policy has been.

The Obama administration bombed people in 8 countries, enforced crippling sanctions that caused widespread suffering in already poor regions, played an active role in 2 coups d'état, allied the US with neo-Nazis in Ukraine and Al Qaeda (Al Qaeda!) in Syria, and played dangerous war games with nuclear Russia.

Below is a non-exhaustive list of Obama's foreign policy horrors. Lest we forget.
