James Blaine: “The power that gives freedom must see that freedom is maintained.”

You can use force only to repel an assault on the public property and aid the Courts in the performance of their duty.

Is any portion of the people bound to contribute their money or their blood to carry on a contest like that?

All these provisions are made to protect the States, not to authorize an attack by one part of the country upon another; to preserve the peace, and not to plunge them into civil war.

The right of the General Government to preserve itself in its whole constitutional vigor by repelling a direct and positive aggression upon its property or its officers cannot be denied.
