Robert Farley makes a lot of sense on the past and future of NATO expansion. As he says, we have no reason to apologize for past NATO expansion, but simply because past expansions have been beneficial doesn’t mean that “NATO expansion” as such is a good thing that needs to be pressed forward. A point I would add is that there’s a difference between extending security guarantees so as to protect countries from Russian coercion and extending security guarantees in order to encourage countries to engage in risky anti-Russian behaviors. There was no sign that Hungary or the Czech Republic ever had any desire to actually pick a fight with Russia the way Georgia did (and has) or that Ukraine with its messy situation including actual Russian military bases on Russian soil plausibly might in the future.
