Have witnessed the obfuscation-laden negotiation cycle too many times before, including during George W. Bush who was supposed to be hard line and feared by the Kims and even HE got rolled and got rolled bad. Result? Smoke and mirrors and the mess we are in today.
If we pay 1 dime in brides we are rolled again. If kim un wants to get sanctions off sll he needs to do is turn over all nukes. No talks needed.
