NATO during the Clinton regime bombed Serbia for almost three months, and today discusses putting "peacekeeping forces" -- i.e. military troops -- in Bosnia-Herzegovina, which is not as yet a NATO member. Parsing the "who said what to whom" is all very nice, but "not legally, not morally, and not in any practical sense" also applies. To both sides, however one determines the sides to be. Given the potential of BRICS, as billions in population, move away from the West in terms of banking and more, "practical sense" seems MIA. What is certain is that Biden most recently said the US must "lead" the "liberal world order." Not my choice. I do want a "leader" to being with. "...in any practical sense."
Moreover, like it or not, by default the US often has to lead. Whether in a street fight or in a crisis abroad, the big, strong kid gets looked to for leadership. The big strong kid in the world these days is the United States. And as in a street fight, even if you would prefer to stay out, one tends to get drawn in when your friends need your help.
