It was the Bill Clinton administration that made the deal that led to this. "It's a good deal"
BushJr did little or nothing.
Obama ignored it even more. Actually ignored intel on the little nukes being developed and kicked the problem down the road.
Now Trump has to deal with it. What will happen? Whatever it is Trump will get the blame even thought the problem was caused by the 3 guys before him. (to Bush's credit at least he did call the Norks one of the three "axis of Evil" although he was laughed at for it.)
BTW watch Clinton deliver the speech on the deal, it is eerily similar to the one Obama gave citing his Iran deal. They both say "A Good deal" for America. HA!!
How long before the Iran deal blows up in our faces? Actually not literally.
We do this to ourselves. This goes way beyond politics. It used to be that politics ended on at our shores. No more, I guess.
