Russia's inability to have a decisive victory against Ukraine is at odds with the idea that it has sufficient stockpiles and launch capability to reduce kiev to rubble any time it wishes. If it had that capability, it would have the capability to destroy Ukraine's defense manufacturing sector - or simply its entire manufacturing sector - which it clearly does not. It's also at odds with the evidence that Russia is launching missles roughly as fast as they can build them.

I guess the question becomes then why did putin start the war without sufficient buildup of missile reserves to flatten Kyiv in the first few days? And why not contract with israeli defense companies for precision missile technology? It doesn't seem like their relations are really that severed even with the whole Iran issue. One would also think China might also appreciate a client willing to battle test their precision military hardware.
