*AFTER* Lincoln started a war with them.
That's fair game, *AFTER* someone invaded them first.
But, of course -- endless lies about it notwithstanding -- Lincoln didn't invade first and didn't start the Civil War.
In fact, there was no Union "invasion" of any Confederate state before the Confederate congress formally declared war on the United States on May 6, 1861.
Indeed, the Civil War's very first military invasions were Confederate forces into Union West Virginia and Missouri, in May 1861.
There were no Union military actions into Virginia until after Virginians formally declared secession and war against the United States, on May 23, 1861.
Further, there's a long list of Secessionists' invasions/seizures of Union properties before Fort Sumter on April 12, 1861.
Secessionist illegally seized Union properties in Union states before those states declared secession in:
Union Fort Pulaski, Savanah, Georgia, seized by secessionists two weeks before Georgia declared secession, January 1861.
