It would take considerable economic incentive, most if not all of which Maduro and his cronies would just steal. It would be lifted sanctions, paid debts, failed investment and simply kicking the can down the road. That, to me, would be the best-case scenario of negotiation. This is a guy who has turned away *unconditional* help for the purpose of control and wild ass nationalism. I respect those countries bringing a diplomatic voice to the table, but there's a region they are in the minority on this.
