Very dishonest of you -- the only "powers" discussed in the Constitution are those delegated by the States to the Union.
The concept of "prohibited powers" is a canard invented by you, for the purpose of flinging sand in the eyes of more honest discussants like Bigun.
Article 10 lists a string of powers delegated to the United States which the States agree not to exercise except through the United States.
Calling them "prohibited powers" in order to drive a wedge between the powers in play and the People is deliberate deception and constitutional subterfuge -- the worst kind of lawyer-talking.
These are all the People's powers, and they dispose them as they please, and ALL powers remain theirs forever. They are not alienated to your favorite federal butt-boys.
The power to admit a state and to approve any change in status once it's been allowed to join is a power reserved to the United States.
No, it isn't. Notice that the States participate fully in the approval process for "adjustments" and the creation (and admission) of new States. This is not a federal prerogative but a shared power.
There is no imperium independent of the People for you and your would-be federal werewolves to use on the People like a club.
Try reading the Constitution some time. "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
No, it isn't. Notice that the States participate fully in the approval process for "adjustments" and the creation (and admission) of new States. This is not a federal prerogative but a shared power.
What constitution are you thinking of? It sure isn't the U.S. Constitution.
