Well the point is to be in 2022 and not live in the past.

I'm pointing out parallels between this and a previous disastrous context and the political clikqte that lead up to it and you're just brushing it off as obsolete, like as a culture we're past that? If this is where we're at propaganda wise I think we seriously are screwed, not even saying "beware, we have seen these talking points before used against people opposed to escalating a war" is considered in bounds?

How did NATO lead into the war?

In the wiki leaks diplomatic cables, officials were warning that continuing expanding NATO past the point agreed upon in the 90s would be seen as provocation by Russia, but they've been expanding anyway despite the potential to heighten tensions.

Since when is it "the left" standpoint to just assume NATO is completely innocent and Russia are just insane batman villains acting out of a pure drive for chaos with no geostrategic goals of their own?

Obviously the invasion is bad but why should we risk a nuclear war escalating the conflict more directly?

But the DSA IC is also opposed to sanctions, which are not warfare.

Obviously they are, they're economic warfare. The goal is to inflict pain on the populace in hopes of causing a domestic crisis in the country.
