Only armed insurrection
Abrogating, subverting, suspending or holding in abeyance the Constitution by use of force OR show of force OR by any other unconstitutional means✔️

Correct Answer Logic:

Article 6(1), as substituted by the 18th Amendment, expanded the definition to cover not only 'use of force' but also 'show of force or by any other unconstitutional means.'
