No, I'm talking about the war in Ukraine.  

Putin wants Ukraine to be Russia.  That's what makes it an existential threat to Ukraine.  If Ukraine didn't fight, there would be no more independent Ukraine.  If Russia stopped fighting, there would be no more war - but Russia would still exist.

Putin fooled you.  He claimed there was an existential threat at the beginning of the war, when he thought he had the power to topple Zelenskys government,  to justify his decision to invade but the reality is if he wouldn't have invaded NATO wouldn't be expanding as quickly and Ukraine wouldn't be fast tracked to join the EU.  Do you really think Russias existence depends on whether or not Putin is able to annex a few regions in the South and East of Ukraine?  Because that's all that's left.  Use your brain.
