Life isn't that black and white. If you think it is then you lack any sort of nuance.

Maduro is no angel, but neither is the opposition. I don't support Maduro, but I support the Venezuelans right to sovereignty in their own ordeals. We can help those who need it, but intervening on one side of a heavily split issue in a country that we don't belong to is a recipe for further disaster. You realize how many dictatorships the US supports? We aren't the good guys. When you do find a good guy to intervene let me know, I'll be waiting.

Also Venezuela IS accepting aid from the UN and other nations. Just not the US since we have a history of not just giving humanitarian aid (Google Elliot Abrams). We burned those bridges and you can't be mad when someone sees it and says "thanks but no thanks"

I understand we are all human, and we should all be treated like human beings, so I understand where you're coming from. But you have to realize that governments aren't individual people and the issue is way more complex then "you're human so I'll fight for you since I'm human too" since there are humans on BOTH sides, and not all them are wholly good or evil.
