And despite anything bad that the current President may have done, nothing that he has done quite compares to herding the entire population of American citizens of Japanese descent in the Western United States into detainment camps. Yeah, I know we'd all agree now that what he did then was a pretty bad thing, but some things are easier to figure out from a distance than they are at the time that you're doing them.
And who could argue with the idea that the right thing to do was to go to war to remove a crazed dictator who was murdering tens of thousands of his own citizens? The biggest question, I suspect, in either case ought to be, "What took you so long to save us?", a question that we might well be correctly putting to the United Nations on the subject of Darfur.
Governments are made up of imperfect men and they will make mistakes.
So will the rest of us.
And maybe some time in the next 75 years, we'll figure out how to do it better. God knows, we haven't figured it out yet.
