The standard for NATO has always been to only accept democracies
As defined by whom exactly? Chinese citizens will tell you that they’re in a democracy and very satisfied with it, much more so than Spaniards for example (my homeland)
I’d even go so far as to make respect of human rights a demand too like we have in EU
EU is literally funding the genocide of Palestinians with 0 economic or political sanctions to Israel coming from governments. By that logic, all of EU deserves out of NATO immediately. NATO also triggered the Libyan civil war through bombing, bombed Yugoslavia, and many NATO countries directly participated in the invasions of Afghanistan and Iraq.
You may want to consider whether the views of expats align with those staying in their home countries.
