As President Abraham Lincoln said:
"The Union was solemnly declared to 'be perpetual.' And when [the] Articles were found to be inadequate to the exigencies of the country, the Constitution was ordained 'to form a more perfect Union.'
"It is difficult to convey the idea of indissoluble unity more clearly than by these words. What can be indissoluble if a perpetual Union, made more perfect, is not?"
Secession is impossible as long as there is a United States of America.
Those who wish secession, therefore, cannot be satisfied.
Since it would be counterproductive to continue to tolerate such people within the perpetual Union of these United States, a process should be created that efficiently and fairly deports an anti-American Unionist to another country.
