So what happens if, say, state/local police or state military forces (let's say the Texas State Guard or that newfangled Florida State Guard DeSantis recently reactivated for the purposes of this hypothetical scenario) move in to shut down a military hospital for attempting a late-term abortion on their soil, after they've passed & activated laws banning or severely curtailing abortion (while there exists no federal law on abortion because the Democrats refused to consider the sort of compromise Manchin and Collins could stomach) as SCOTUS has just recognized is their rightful prerogative? Would that qualify as a latter-day Fort Sumter?
Well, I guess if you absolutely have to have a Second American Civil War, having it pop off because of baby murder is a better reason than most.
