Apart from an Article V convention, we are running out of peaceful options.
Going back to at least 1660, English speaking peoples have held conventions to deal with inadequate or oppressive governments.

But, the fact remains that conventions of the sovereign people are well established in our history and should be resorted to when circumstances, such as now, compel us.
