I'm arguing that the US is largely isolated from the economic effects of the war, and that this is evidenced by the lesser inflation spike in the US compared to Europe. America is barely exposed to the Russian and Ukrainian markets and is even a net exporter of some highly impacted commodities like natural gas.

That doesn’t undo the inflation that already happened! The sanctions are priced in.

Nobody said it undid anything. If what you said was right, though, then surely the rates would stay high given that the circumstances you claim are causing them haven't changed? Since they haven't, it seems unreasonable to pin the blame there with no further justification.

It is, but I just wanted to highlight the multifaceted ways the burning money pile in Ukraine is causing inflation.

I think that actually you just started with a conclusion you wanted to reach - that whatever America is doing is bad in all situations - and said whatever came to mind to get there. The war in Ukraine does drive some inflation, but the US is largely isolated from it, and this is further evidenced by the fact that American inflation was already high before the Russian military movements in late February 2022. I mean really, can you think of nothing else that happened in the past few years that might perhaps have reduced production and trade across the world, thereby increasing prices? Something that has, unlike the Russian invasion, become less of a problem in the past year?

I'm sure that choosing a 0.4% decrease in government spending over equipping millions of people to defend their homes from a militaristic empire is somehow a move for human rights in your eyes, though.
