I believe Ron Paul has seen a lot during his time in Congress, and is no longer restricted to what he can say, so as not to offend voters. Sometimes the truth hurts.
Who can deny, that since WWII we have played the role of the worlds sheriff? The 1st invasion of Iraq, was warranted by the sheriff, as was the Bush administrations Iraq war. It went very well from the start, but as soon as the reason to go to war was over, instead of packing up and coming home, our leadership has spent the past 10 years Nation building.
A lot of people in high places make a lot of money Nation building. Only the tax payers and the warriors pay the price for it.
