Thing is, will it? The Venezuelan state still seems to be running itself, with vice president and ministers still occupying their posts. Maduro himself isn't some embodiment of PSUV and the party can continue existing and governing without him.
Simply kidnapping Maduro without leaving behind boots on ground does very little besides intimidation. That can work for extracting concessions, but not for ruling a country. Either the rumoured second attack is coming soon or this might be negotiation tactics for full privatisation of the oil but leaving the government be.
