"The Union was formed by the voluntary agreement of the states;
and these, in uniting together, have not forfeited their nationality,
nor have they been reduced to the condition of one and the same people.
If one of the states chooses to withdraw from the compact,
it would be difficult to disapprove its right of doing so, and
the Federal Government would have no means of maintaining its claims
directly either by force or right."
