We were attacked at Fort Sumter, as at Pearl Harbor.
The South suddenly attacked without warning, killed 3000 of our soldiers and did 500 billion in damage, and thereafter threatened all our shipping interests in countless other countries?
Wow! I didn't know that.
You do know, I hope, that Ft. Sumter is in South Carolina, don’t you? And that South Carolina had seceded, and was no longer a part of the United States; and that Lincoln not only refused to peacefully leave Ft. Sumter, but instead had ordered it be reinforced and resupplied? THAT was an act of war, and before Beauregard ordered the bombardment of Sumter.
