Why S&P hasn't moved since war re-escalated

TBH, I really don't understand what's happening with the market right now. It feels like all the war-related news isn't having much of an impact anymore. At best, it seems to prevent the market from moving higher for a while, but it doesn't seem to trigger the kind of sell-off we saw before. What I'm struggling to understand is what's actually so different now compared to April, when the market reacted much more negatively. Back then, similar geopolitical tensions caused a significant drop, but now investors seem to shrug it off almost immediately. Is the market simply pricing in these risks now, or is there something fundamentally stronger about the current environment that's outweighing the uncertainty? I'm genuinely trying to understand what has changed.
