I remember a late 1980s graphic novel mini-series where through a series of multiple assassinations (taken place over a period of a year) a military coup took place led by
junior officers of the US Army. They declared that following the blowing up of the White House (by the coup plotters,

and for the 2nd or 3rd time in the series IIRC) they were "forced"

to declare a state of national emergency (under whose authority!?) until "the situation could be stabilized".
Whereupon the coup leader was told by his minions that New England had just seceded from the Union to form its own country. As the coup leader (a colonel!

) is watching the electronic display map of the USA, as he quickly watches the South secede and re-form the Confederacy (NOT
THAT Confederacy

), the NW USA secedes and applies to Canada for protection, California secedes into a Anglo-Hispanic nation state, as does Texas, and New York City declares itself an independent City-State.
The beautiful part of the story is one of the face of the colonel, a career intelligence agent and assassin, desperately trying to think "Now, who can I assassinate to fix all this!?"

Moral of the Story? Don't break something you can't fix.

I can well imagine things going the same way had the Japanese coup-plotters "succeeded". Rover caught the car. NOW WHAT!?
