[Grand Old Partisan]

What Madison is saying, and what a good book on Madison or the Constitution would explain, is that the "violation or abuse" of the compact he is writing about is the secession of a state or states. In other words, a state could be kicked out of the Union by all other states seceding and setting up their own country without that state -- such an action would be a "violation or abuse" of that state.

Here you show yourself to be seriously out of your depth, and not worth any more of my time to debate. Ciao, Gianni!

No. Read the sentence. That's not what he is saying. It could not be more clear.
