In the media, I think there is some hesitant 'which way is the wind going to blow' and 'which sources on this can we trust' going on.
For every day people, I think a large part is fatigue - same as pp mentioned what's going on in Iran or the genocide in Congo or so many other horrific things going on. We can only focus on so many things, and I think it's harder when we're left feeling that there is little we can do about it.
Personally, I've spent the last decade or so feeling like I'm in perpetual 'the US government has done what now?' to the point that this is no shock or much beyond 'ugh, not again' type of feeling.
Drug runners who are flooding a country with deadly substances and killing untold numbers deserve all they get in my eyes.
There is nothing to suggest those murdered were drug runners and excusing deaths by a government is how the US, UK, among others have gotten though many, many coups in the past. The issues in Iran? Directly traced to the US and UK coup over oil. The genocides in Congo - the UAE is funding weapons and drugging up kids for resources. The regular practice for power grabs and control aren't that subtle - they sell a tune about there being a threat, and aim no where near the cause.
If this was about drugs, Venezuela was the wrong target. It isn't a stronghold for either fentanyl (components are made in China and India, the processing and running mostly from Mexico with a smaller amount coming from Canada from the US's DEA own intelligence reports) or cocaine (it's called Columbian marching powder for a reason, largely grown and processed there, Bolivia, and Peru) or really any other drug. Some civilians become drug runners for gangs , and some governments either support or turn a blind eye to it, but Venezuela isn't unique or particularly represented in this issue compared to several other nations even by the US's own reports.
Even if their president is everything the news is saying and the people are overjoyed, the US government is not doing this out of any altruism or to help stop the opiate epidemic or anything else killing many ordinary people. They have and merrily put in again someone far worse if it gets them what they want.
How many Americans have been killed by drugs brought in from Venezuelan crime gangs? Have you got any sympathy for them? Thought not.
And all the other crime gangs? Or the American health care system where a lot of opiate addictions in the US begin? Or the lack of resources in addiction services from the US government?
I used to live in the US, I've seen the opiate epidemic first hand, all the ones I've known started as prescription drugs that ran out before the pain did, then they had to find their own way to manage & no help when it became too much. Killing more people in Venezuela isn't going to change any of that.
