That would seem to make it fall under the 10th Amendment.

It would not seem. What don't you understand about the term “Perpetual Union”?

From the Articles of Confederation and perpetual Union;

Article XIII.

Every State shall abide by the determination of the United States in Congress assembled, on all questions which by this confederation are submitted to them. And the Articles of this Confederation shall be inviolably observed by every State, and the Union shall be perpetual...

Good point. As Lincoln explained, “more perfect” meant “stronger.”

The Articles of Confederation were determind to be unworkable, and were replaced by the Constitution, which became the supreme law of the land. As far as I know, the Constitution does not anywhere use the term “Perpetual Union”.

[OneWingedShark]

...so you’re citing a clause in the Articles of Confederation which the Constitution superseded and replaced in order to justify qualifying the latter’s concept of ‘union’ as perpetual?

That is highly dubious reasoning.

The “Articles of Confederation” were found to be flawed and were discarded with the institution of the Constitution.

Well,our supreme law is not the Articles of Confederation,although I do not think secession is a good idea.
