There really doesn't seem much doubt that we were lied to in order to ensure that we went to war.

Even if the good consequences of that war outweigh the bad consequences, that doesn't change that. It's possible to argue that the lies were justified, but that is not the same as pretending they weren't lies - and what is the point of trying to do so?

"War is a profession by which a man cannot live honorably; an employment by which the soldier, if he would reap any profit, is obliged to be false, rapacious, and cruel." Niccolo Machiavelli
