There was nothing sensational about what I posted. A non-biased news article and 2 blog posts from people who have been, including one from a guy who is from there. Venezuela is one of the most dangerous countries in Earth and to be honest, you are safer in Baghdad than Caracas. Last year alone 24,000 people were murdered in Venezuela. Someone is killed there ever 21 minutes. There is 1 gun for every 2 citizens. If that doesn't give you pause then so be it.
The threat of terrorism in Sochi was pure speculation. What is happening in Venezuela is not.
Now, you also asked how unstable the environment is there. Violence aside, international mail delivery has been suspended there. Delta just announced yesterday they are joining the long list of other airlines in reducing service. They are running out of toilet paper. They are in the midst of a drought and rationing water.
