To the contrary. Lincoln started the country's bloodiest war.
Lincoln fired on Fort Sumpter? /s
Yeah, right after the rebels started the war against the Union.
If you wish to see how the Democrat mind works, read DiogenesLamp's posts -- he starts by redefining terms until up is down, red is blue, etc.
In this particular case "starting war" is not when Confederates fired on Fort Sumter & forced its surrender, oh, no, that was just kids peacefully playing in their sandbox.
No, civil war started when Lincoln "launched his war-fleet against the Confederacy."
Never mind it was a resupply mission to the Union troops in Fort Sumter with orders, in effect, of "no first use of force."
Never mind Confederates had been waging low-level war against the Union since December 1860, with no serious response from either President Buchanan or Lincoln.
Never mind Confederates quickly declared war against the United States, May 6, 1861, not important.
What matters to the mind of a Democrat like DiogenesLamp is that Lincoln's "war fleet" demonstrated less than abject surrender to Confederate demands, ergo, "Lincoln started war".
