He’s pushed boundaries on the Ukraine war. Both the Russians and the Ukrainians would be willing and capable of assassination if it helped war goals but I think he just hasn’t quite crossed a line to either side where he’s better off dead.

Eg. Starlink connections in Ukraine are geofenced. Which would piss off both sides in various ways. Pisses off ukraine because they have legitimate targets outside the fence and pisses off russia because they have legitimate targets inside the fence. That’s walking a fine line.
