If Venezuelans returning from US were scrutinized, there wouldn't be such as mess today. If Americans didn't influence Venezuela, there wouldn't be such a mess today. Spying's become a fashionable trend for some powers to gain a competitive edge as well as a degree of authority in the region of interest.

The western (free) world has had its chances to lead by example but lost to the ones who have learnt from their mistakes. Venezuelans are opening their eyes today while Chinese have realized "a few days ago" what it would be like with the foreign influence on their soil. Venezuelans' American educated Guado has his fingers in the current power outages which is why Chinese politicians won't be able to accomplish (probably ever).
