The people making money out of other people's misery are the Government connected insiders who have squirrelled away $300 Billion dollars of missing oil money  - THAT is economic warfare.

Economic warfare is taking business that were providing services and jobs to Venezuelans, nationalizing them, and then denying them capital so output collapses;

It is taking productive farms and handing them over to people who have no experience of farming so output collapses and the country can't feed itself;

It is giving away greater and greater amounts of dwindling oil output for free because you have loaded the country up with debt;

It is giving entire industries away to foreign Governments, then paying them a premium for useless products.

And who sold GS the bonds? Some pension fund who was afraid they couldn't meet their obligations when Vene finally implodes?
