Let's try this again
Amendment X
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.
I'll even break it down for you.
The powers not Delegated to the United States by the Constitution (i.e. those powers that were not specifically GIVEN to the Federal Government)
Nor prohibited by it to the states, (i.e. the Constitution does not prevent a State from performing an act)
are reserved to the states respectively, or to the people.
(i.e. the states and or the people reserve these rights to themselves)
Where's your paragraph that says
"The Federal government has the right to force States to stay in the Union by force of arms"
hmm?
First you must understand what the Tenth was referring to and what it was not. It was NOT referring to any acts by a state which would affect the structure of the Union. It was referring to those acts of states which ONLY affect the internal aspects of a state. Since secession affecting the entire structure of the Union it is unconstitutional.
How can a State law (secession) overrule the Supreme Law of the Land? Remember that is what the Constitution is and says it is.
The reason the tenth was written was to reassure states that their internal affairs were to remain under their control not a national government's. It was for the most part also a re-assurance that there would be no federal interference with slavery.
Your hypothetical comment on what my Constitution says is incorrect. It is for me what it said it is The Supreme Law of the Land.
