Wow. I don't even think I know how to respond to that.
I don't know enough about the detentions to warrant a response, pardon my ignorance. I do know that treason is the usual charge, it seems he could have been preempting the secession of Maryland. That seems like it would have saved lots of lives to me.
The 'warships' sent to Sumter were going to restock the fort which was out of supplies. You are right in one manner, they were sent to pressure a settlement of some sort. Not to start the war, but to force the south to make a decision-- they just made the wrong decision.
As far as 'states rights' are concerned -- I used to be totally on your side (I'm pretty conservative myself). The problem with the argument is that 'states' do not have rights. People, citizens, have rights States have powers -- per the 10th Amendment which grants all
powers not given to the federal government to the states (which all those states ratified to enter the union). Nullification and secession completely undermine the federal order of the constitution. While the feds should be limited, as it is in the constitution, the south was out of line by seceding with the election of Lincoln in 1860.
Lincoln argued long before the war that slavery should not be expanded
into the west. And whatever our contemporary beliefs on Lincoln, I think we all have to agree that slavery had to be eradicated. The south's economic system was corrupt because of slavery and it had to be replaced. Unfortunately no political compromises were going to allow the gradual destruction of the institution as the Founding Fathers had hoped, the Compromise of 1850, Missouri, and Bleeding Kansas prove that. Yes, the Emancipation Proclamation was a tool of war and politics when it was issued. The Union aligned slave states on the border: Kentucky, West VA, Maryland, etc. were not subject to the emancipation proclamation. It was meant to foment slave rebellion (against the CSA govt) in the south and give a sense of moral superiority to the Union cause. In the end, it served to make the practice of slavery illegal in the US -- finally.
I think the Union was worth fighting for, I'm glad I don't have to have a passport to go south. And I believe Lincoln to be a decent guy. I feel bad for him that it was he that had to deal with it, but thankful it was a man like him. We are all better off.
