Russian nukes

As a non military person sitting on the sidelines it appears that technology is changing the face of war in ways that some countries do not realize. We have seen in Ukraine that small inexpensive missiles can destroy heavy armored tanks and shoulder held missiles can bring down planes. China announced recently that they are building destroyers and the Ukrainians recently destroyed a Russian ship in the Black Sea using a Harpoon missile. Unmanned drones flying thousands of miles from their control pilots can fire missiles at targets. Some drones armed with missiles and/or bombs can fly on automatic pilot to their targets. Russia lost 150 aircraft in the first month of the war. Russia was expected to control the skies in the first few days but technology spoiled their plans. If their nuclear forces are as inept as their air force they are not likely to challenge the US to a nuclear fight. The constant fear is that someone in power will act with reckless abandon and start WW 3
