Gettysburg Address

[maharba]

It was universally known that Massachusetts and other states had threatened to and might indeed Secede to form a new Confederacy at any time, which would dissolve the Union. Neither Lincoln nor any one else had ever taken exception with their rights to secede. And Texas had already seceded from Mexico, which Lincoln had endorsed. He had already seen the 1832 BlackHawk War, and now minimized or negated any major war threat from American Indians by his speech.
Maybe his relatively conflict-free outing in the War falsely convinced him of the present and future negligible capacities of Indian Tribes. So there was some history past and more to come (the Mexican War), which would affect Lincoln's political future. Maybe, all that had much to do with Lincoln's omission in the Lyceum speech of the Union?
