We don't need to deal with hypotheticals, because many countries near the US' border did attempt different govts over the years, and the US did interfere with their sovereignty, successfully in all cases (el Salvadaor, Guatelmala, Honduras, Nicaragua), except one (Cuba).
I assume that you supported US interference in those examples then? Because if you didn’t I don’t see how Russia’s interference in Ukraine could be seen as acceptable because the USA did shitty things in the past. Understandable, sure, but just as I will criticise the US for all the bad things they’ve done, and do (and there are plenty) I don’t see why we should use their sins to justify the yet to be committed sins of others. Would be a race to the bottom, no? Maybe let’s just criticise bad things as being bad, try to prevent more bad things from happening and attempt to hold those to account who have committed bad things in the past. We can choose to criticise actions, not criticise actions solely based on who we choose to align with (US or Russia here).
