"Rebels?" "Rebelling against?" Would you care to cite a specific constitutional clause that prohibited State secession?
Of course not...

I already did. The President is delgated the power of being Commander-in-Chief over all citizens of the United States and sworn an oath to defend all U.S. citizens and the Constitution of the United States.
The State legislatures do not have this power. the State Executive branch does not have this power. The States themselves do not have this power over citizens of the United States due to the Constitutional FACT that this power is delegated to the United States President in the Constitution.
