Drugs are not the issue here. It's the bullshit reason, because the real reason is so ugly it cannot be see the light of day.

oh, its not that scary or offensive. Maduro was an illegitimate dictator, just like all of Trumps other friends. but he just wouldn't play along. ultimately thats why the US is so intent on supporting corrupt governments. your son-in-law gets a big contract from the US, and my LLC gets a lease to do mining operations and we're all happy now right? Trump gave Maduro a deal he couldn't refuse, and he .. refused! what's a Don supposed to do, if Maduro can refuse than everybody else is going to get ideas.

So big international corruption schemes are the real reason.

Drugs are merely a cover story: sand in the eyes of the public.
