So much hate in this thread - but no surprise, as most forum members seem to be somewhat limited in their geopolitical view.
Putting this into context: two countries are isolated from the rest of the world and banned from trading with many other countries. Certainly not without good reasons, but in a larger context these governments are not more evil than several other very large countries. So one of these isolated countries sends a delegation of government officials to another one, aboard a civil A340-600, for business talks, and this is really all we know at this point. Were there passengers on board, and how did they book their tickets? Read the articles. This was not a scheduled passenger flight, but a government charter. Is the "Terror Express back in the air"? For chrissake, there are about 100 Terror Expresses in the air right at this moment, and none of them originated in Tehran.
Come to Venezuela (if you dare...most people don't) and then tell us that this government isn't more evil than that of most other countries (big or small). Watch people get robbed, eating from the garbage on the streets, getting their drinking water from a small river (looks more like a sewer) running through the heart of Caracas, children with leukaemia telling their mothers "Mom, stop struggling trying to get me medicines, it just makes both of us suffer, I'll rather die", entire cities go without electricity for 7 days in a row... How can you even consider comparing this murderous band of thugs to a government of any other country, apart from possibly North Korea? And in Pyongyang, you can walk the streets at 2am in total safety, whereas here in Venezuela you run the risk of being robbed and killed at 2pm, anywhere...a shopping centre, in your car, walking out through the door of your house...
Oh, and Venezuela isn't banned from trading with the World. Where did you get that from? The sanctions in place are against a handful (well, I think it is some 50 people by now) of the top brass of Maduro's gang of thieves. And if you buy something from the Venezuelan state, you have to make the payment to the Government that is upheld by the constitution, not the one clinging to the power by electoral fraud. I think that is quite reasonable... Those are all the sanctions that are in place.
With this in view, this flight can have no other motive than a) planning more repression of the Venezuelan people; b) delivery of arms and/or military advisors c) siphoning off a few tonnes more of Venezuelan gold/cocaine/rare minerals into Maduro's private stash or d) a combination of some/all of the above.
If you (and some other people on this thread) knew the reality on the ground and the true suffering that people here go through every day and every night, you would quickly change your opinion.
I invite you to Caracas for you to see. I will personally guide you. Take out a good life insurance before arriving, though.
