Lincoln managed to do that AND work with a democratically elected Congress AND operate within the guidelines of the Constitution AND hold an open election where he stood a very real chance of losing. Like I said, Pinochet was the very antithesis of Abraham Lincoln.
One could point out the lengths to which Lincoln had to go to to accomplish his goals. You'll note the South was not a part of those he worked with, democratically-speaking, nor was the suspension of the writ of habeas corpus exactly "Constititutional." As you've been told repeatedly, he understood it was not a mutual suicide pact. It was a very messy situation, far more so than anything Chile experienced, but it had to be done, or what could've emerged would've been a far greater disaster. Pinochet did a cleaner job than Lincoln, but both were heroes, nonetheless, despite your sleazy innuendoes and comparisons to bonafide monsters.
