Russia can’t escalate any more than they already have without directly attacking the US or with nukes, and in both cases, it’s suicide. They are struggling to take on Ukraine, let alone the US, and literally no country of influence would back them if they attacked or escalated to nukes.
I agree with you, but that's not what's being discussed here. If it were to come to kinetic warfare, Russian wouldn't stand a chance against the US as evidenced in Ukraine.
