Nonsense, it was the refusal of the Union to remove its troops from Confederate territory,

There was no "Confederate territory."

As the Constitution clearly declares, all state acts - and that includes "Ordinances of Secession" - are subject to Federal review.

No state can unilaterally alienate territory.

“As the Constitution clearly declares, all state acts - and that includes “Ordinances of Secession” - are subject to Federal review.”

Nonsense, you’ve tried that argument before, and it’s still as ridiculous as ever. To interpret the Constitution that way eviscerates the right to self-governance, and that is a right which pre-exists and trumps even the Constitution. The Constitution depends on that right, without it, the Constitution is illegitimate, so your argument is self-defeating.

No state can unilaterally alienate territory.

Except when 13 slave holding states asserted a right from God to do so, and did exactly that.

You are going to have to pick a side. Either both sides had a right to leave, or both sides did not.
