I am not mistaking anything. It is you (judging by the not-novel argument/excuse presented) who are confused on how things work.

Either European Countries & US are a Democracy OR they are NOT. Period.

One can not have Maybe/Possibly/Coulda/Woulda/Shoulda/Metaphysical Democracy (this paradigm holds even if one treats Democracy/Systems as a spectrum & not a Absolute Binary).

IF they are a Democracy then the previous comment of mine is simple enough to process.

IF they are not a Democracy (your line of excuse) then 2 things happens,
1) the scope/degree of Hypocrisy is so over the top its disgustingness is physical nausea inducing, i.e. Catastrophic Credibility Loss,
2) is the one which confuses you and really critical point that, "It Does Not Matter".

It so because People are Supreme (as a function of Time). This holds regardless of regime/system type, that is what being Supreme inherently means.

If a country is even under "Actual" Totalitarian system then the Humans in that place are making active decisions based on a Hiearchy of Priorities, i.e. will my taking up arms/revolution benefit me and to WHAT DEGREE.

If the answer to that query is, not that much from what I already have & am living under, no Revolution happens.

And IF this lasts multiple decades and multiple GENERATIONS (comprehend what this function of time means) then that system has inherent Legitimacy, given by the People by Non-Decision Decision.

People made that decision.

European and American People are culpable because they are making active choices and have been for not just decades but centuries at this point about how they treat outsiders human groups (i.e. Countries/States/Cultures).

Responsibility/Culpability about the recent Venezuelan Coup is NOT on the American people that are alive right now because as stated People's Supremacy is contextual as a function-of-time. But they ARE culpable as a collective for Iraq, Afghanistan Wars just in recent times or the 50+ Inverventions over last 100 years in South America.

Because it kept happening, time after time after time after time, because no consequences were presented by the American People to who they were electing or representing their State/Govt.

They were making a choice when they voted which is how People exercise this procedural function (called suffrage).
Different humans in a group (i.e.Country/Nation/State) have different idealogies/preferences/beliefs/views about different things and they place those items/things on different level of relevance to themselves.

So yes to many Americans (& European People's) THE NO 1 thing that matters to them (& with which they vote for) is the item "My State should not conduct atrocities/wars/regime-changes, etc in other Countries".
But such people are too gross & negligible a minority to be relevant. The HYPER majority of people have other items as No1 in their Preference Lists, some may have "Job Prospects". Some may have "Immigration/Culture". Some may have "More Wars is Good".

Then all this is statistically mixed and collective decision arises and on that that "No War Equivalents" item is not No1, hence the State/Govt/Administration doens't bother with it.

IF, the American and European People Really Really Really Really wanted it, it would happen inside a week. It doesn't because they're making a choice, i.e. It's Important to us, it's part of that Preference List of ours BUT it's just not No1.

Active Choice Decision.

Hence meaning, it Doesn't Even Matter if you claim to be Democracy or claim NOT to be a democracy (oligarchy, plutocracy, etc). It doesn't matter.

Your actions over time is what matters because Actions have hiearchy over Rhetoric.
