I beg to differ:
Before Obama, N. Korea did not have any nuclear potential; It had the backing of the Red Chinese and/or Soviet Russia (at varying times); We had an armistice.
Since Obama came to power, N. Korea has developed the bomb, lost pretty much any support from its ally, and cancelled the armistice. Yet Obama's only action is to cancel a missile test.

I didn’t realize this thread was only about Nukes
