Russia, controller of the worlds largest arsenal of nuclear missiles, currently has foreign troops on its land that are attacking it. The US is publicly signalling that this might not be going far enough to pressure the Russian homeland [0]. This attitude floors me. I can't figure out if people legitimately believe that we can just ignore the nuclear war risk because they can't conceptualise how bad it'll be [1] or if the plan is to purposefully explore for a limit where Russia snaps. I suspect we've literally never seen such reckless escalation against a nuclear power.
