I don't think the US is above nuclear blackmail.
In fact, US nuclear doctrine isn't MAD like most people think.
It is preemptive counterforce.
This means the US would attempt to destroy all adversary nuclear forces in a first strike which prevents retaliation.
When people say "Russia has 6k nukes" they're technically correct, but in reality there are only about <200 hardened nuclear targets in Russia that would need to be nuked in order to prevent Russian nuclear retaliation (And this isn't even getting into how the US was very good at tracking Soviet nuclear subs etc)
That's because Russia's missiles are heavily MIRV'd, and there are roughly a thousand or so total warheads ready to launch.
Situation's similar in China although it is clear PRC planners realize their nuclear deterrent is not adequate and have adjusted accordingly.
Bottom line is (and they could be overconfident here), they think they can come out of MAD on top.
This is extremely dangerous as it greatly increases the chance of them using nuclear blackmail.
Russia has launch on warning and constant Topol patrols in the middle of Siberia. US couldn't track Scuds in the middle of a desert with air supremacy and physically overflying the search area. A Topol with its engines idling under a tree with no planes overhead is effectively invisible.
Same with China. China's filled with mountainous jungles and urban areas. If they can't kill Iraqi Scuds in the desert what are they going to do about trying to find TELs with thousands of urban tunnels, forests and mountains where they don't have any overflying real time sensor assets?
I also decided to fact check the 200 targets claim. It's wrong. I know who it's from, some dumbshit reddit troll who sexpats in Taiwan and thinks he's a white Taiwanese.
So there's 18 mobile Topol-M, 60 stationary Topol-M, 36 original mobile Topols, 136 Yars mobile and 24 Yars silos, all listed under Operators. Already more than 200 so I don't need to count anymore.
That's not even counting Russian liquid ICBMs, subs or IRBMs.
just 2 of their most recent ground based solid rockets.
They also stopped publishing data when US dropped out of START.
