OK, I went through that wiki about 5 times and I can find no mention of economic sanctions against the people of Venezuela. Here's what I did find:
"On September 15, 2005, President Bush designated Venezuela as a country that has "failed demonstrably during the previous 12 months to adhere to their obligations under international counternarcotics agreements." However, at the same time, the President waived the
economic sanctions that would normally accompany such a designation, because they would have curtailed his government's assistance for democracy programs in Venezuela." Sanctions were waived, ergo, no sanctions.
"On May 28, 2014, the United States House of Representatives passed the Venezuelan Human Rights and Democracy Protection Act (H.R. 4587; 113th Congress), a bill that would apply
economic sanctions against Venezuelan officials who were involved in the mistreatment of protestors during the 2014 Venezuelan protests." These sanctions were against individual officials, not the Venezuelan people.
"On March 9, 2015, the United States President, Barack Obama, signed and issued a presidential order declaring Venezuela a threat to its national security and ordered
sanctions against seven Venezuelan officials." Again, sanctions against individual officials, not the Venezuelan people.
That's it. Besides the bibliography, these are the only mentions of sanctions, and none of them are in any way sweeping enough to affect the Venezuelan economic disaster as it stands. They're all against certain individuals, not the economy in general. As for 'intrigue', when was the last political interaction you heard of that didn't have the flavor of intrigue?
