The End Justifies The Means?

I can't help but wonder what some of these people think. Why was this war (Iraq) pushed? With Afghanistan, we knew the Taliban were in sympathy with and protecting our enemies.
But regardless of all that, the deceit involved is what bothers me. When the Politicians think they have to lie to the people it is a bummer. Do they think they're so much smarter than the rest of us? But we need to remember that this is not confined to one party. Johnson did the same thing with Vietnam in that Gulf of Tomkin thing.
But one thing leads to another and we see this same attitude in those "Enhanced Interrogation" techniques.
And The Fuzz believes that this attitude of "The End Justifies the Means" is what will bring America down. We can already see it happening.
