A defensive alliance is what it says on the tin. If you want to take umbrage with the aggressions of any individual country, by all means do so. But don't turn NATO into your own personal bogeyman because one of its members did a thing you didn't like irrelevant to the mandate of the alliance. That's a bad faith argument.

If I make a promise that I won't punch you and you go punch someone else, that doesn't reflect on my promise not to punch you.

If that aircraft carrier was acting under NATO's auspices it is absolutely relevant to the argument. If it wasn't then it is a strawman and should be called out.
