EG playing devils advocate, if i was russia i would have(based on their promotions) used their so called precision missiles to in unison take out precision strikes on all ukrainian political buildings and military bases and void ukraine of any military response in one day

Russia has also shelled the city of Kyiv and other Ukrainian cities, as well as military installations throughout Ukraine, since the early days of its invasion. Explosions were recorded in different parts of Kyiv, but in the central part, where the central authorities were located, there were practically no explosions. Most likely, Ukrainian air defense worked well there, which did not yet have the ability to effectively cover the sky over all of Kiev. But in response to a corresponding question, the Kremlin then said that they were not shelling the buildings of the central authorities of Kyiv because there was someone to sign the surrender of Ukraine.
In any case, later Putin’s army tried to destroy the central part of Kyiv, even using their new “dagger” missiles, but by that time Kyiv was under relatively reliable air defense protection. But rocket attacks on Kyiv and drone attacks have continued for the third year.
As for military facilities, the command of the Ukrainian Armed Forces secretly moved equipment, primarily aircraft, to alternate deployment sites before the attack, and this made it possible to preserve the bulk of aviation and other military equipment of Ukraine. Because of this, in the first months of a large-scale war, the Russians suffered staggering losses, forcing the aggressor army to withdraw its troops from central and northern Ukraine.
