> The civilian casualties in ukraine since 2014 is about 3,000. Not sure where you get tens of thousands.

He is clearly referring to the 2022 Russian invasion of Ukraine.

> You do realize that far more people died in iraq, afghanistan, etc than will ever die in ukraine right?

Iraq was notably not a NATO operation, and Afghanistan was a protracted twenty year long war that saw some ~50 000 civilian deaths. At this point, considering the intensity and very high casualty numbers in the 2022 invasion of Ukraine, it's hardly credible to claim to know how many will "ever die in Ukraine" if we don't even know where that war is going, let alone how and when it will end. Above you also brought up Syria, which is again not a NATO operation, and Libya, where some 10 000 NATO air-strikes ended up killing less than hundred civilians [1]. Would it be better if those 40-70-ish people not have died? Obviously. Is an amortized 0.7 % chance of a given air-strike killing one civilian showing that NATO targeted civilians? I think not. That brings up to the NATO bombing of Yugoslavia, which if I recall is the only time NATO actually did something without UNSC (~everything) or Article 5 (~once) authorization, solely based on all NATO members agreeing to do it. Personally, I think it was the right thing to do, but it was done the wrong way legally and operationally.

[1] A popular claim on social media is that NATO killed over 500 000 civilians in Libya, which would amount to about 10 % of the population at the time.
