America is not like Rome, because America is 50 different countries within an United States
so it's practically impossible to overthrow the Republic as was done in Rome
Washington doesn't have anywhere near that much central control
I will say that I agree with Marty Hash
there has been a soft coup d'etat by rigged election and this has resulted in a military Junta taking control of Washington
this however does not mean the Republic itself has been overthrown
the entrenched interests in the beltway have made a Junta, but Washington doesn't actually have that much domestic power
America is much more decentralized than Rome, for this very purpose
I would say the Junta in Washington has power over the overseas operations, but vastly less at state level in America itself
