Worst President in history ?

[Raistlin]

Andrew Johnson.

He tried to undo the freedom that Abraham Lincoln gave to the slaves, and that was just wrong.

No, he didn't.

He didn't undo anything, but he didn't do ANYTHING to help start rebuild and intergrate the South. He let black codes and other constitutional disgraces run rampant, and pretty much just sat back and watched.

EDIT:

So if we keep to ourselves and let the UN do its job around the world, then we're letting others be slaughtered and starve...but if we take action against our inevitable enemies because the UN is incompetent, we're overbearing and militaristic? Where's the middle ground?

There's the problem right there. "Inevitable." Iraq hadn't done anything against us. The "preemptive strike" bull was the worst possible reason. Are we now going to throw people in jail for being "inevitable murderers?"

How many terrorist training camps are there in Ethiopia? How much does the Burmese government spend toward providing weapons and training to people who wish to slaughter as many civilians as possible? How many of his own villages has Mugawbe cleaned out with the nerve gas and blistering agents he's sworn to use against the United States? Ever stop to realize that Saddam was a threat to everybody, and is no more?

But that wasn't the reason we went into Iraq. "Preemptive strike" and "weapons of mass destruction." Neither of which had much in the way of objective evidence. I could make up justifications for Hitler's regime, but that doesn't mean that any of them would be part of his actual rational. And I repeat: the ends do NOT justify the means. The means must be justified in and of themselves.
