I've seen a lot of the headlines spilling out of NY Times, WaPo, Fox, MSNBC, et al. and they're not arguing in favor of the US going to war with Russia. That's a very rare argument.
Almost exclusively the arguments are about how to respond after Russia invades Ukraine, in terms of the severity of sanctions. As well as if the US should be (or can) doing anything right now to dissuade Russia from invading.
I'm also seeing no common arguments in the US media in favor of a NATO war with Russia more broadly.
Go look at the home pages for CNN, Fox, MSNBC, CNBC, ABC, CBS, NBC, Washington Post, NY Times, LA Times. Where are all the arguments in favor of war with Russia? All I'm seeing is a lot of discussion about the context of Russia being on Ukraine's border and the odds they'll invade or not, and what non-war response will be appropriate afterward (including eg moving more US forces into other eastern NATO nations as support to the security of those nations).
