The unspoken reality is that the Americans overwhelmingly want to nuke China as a first strike. Even a great chunk of their citizenry want to do this or think it is necessary and a "good thing". That's how effective 20 years of constant anti-China propaganda can achieve and what 70+ years of anti-"communism" propaganda can do. Contrast with asking Chinese citizens whether they'd wish death and destruction on the US and most would reply no. The desire is unbalanced.
We know China has HGVs and HGV carrying warheads (presumably since that's a top priority) since at least 2019 in service and if China shows one type just to make a statement, they have many, many types, fitted on multiple platforms. My suspicion is that not only has China long ago been holding over 1000 warheads but also increased DF-31A/x, DF-41, JL-2, JL-3, and DF-5A/B numbers and the nukes they carry. To complete having a top tier nuclear capability, it just needs H-20.
If it didn't already have all that, the US would have conducted a surprise first strike long ago. That's the unspoken truth. They already set up all the narratives and priming the press and so on. They do not need some stupid pretend congressional oversight on all these things. They only have a facade of civilian leadership but their dictatorship operates just differently the all the other ones. Powerful western nations are just as totalitarian. The rules are just there for lower matters and to provide some semblance of all that "nice stuff" and civility but when the poop hits the trousers, it is total dictatorship and worse, it's an invisible rule with even less accountability than CCP. At least with the CCP it truly is a civilian comprised government and dictatorship with a person and a face at the top along with a genuine congress that just operates differently to US facade congress.
I bet intelligence agencies in both nations already know far more about these matters and have for a while.
All these whispers of rods from space and orbital nukes are just games between those intelligence agencies and we're missing all the context and info necessary to interpret posturing.
