It is learned, but a learning chiefly ignorred by our DC Leaders . . .
"The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants."
-- Thomas Jefferson
We do know this, but the same holds true for any revolution against tyranny. The Vietnamese, the Iraqis, the Afghanis do not. They have never known freedom, and so have never learned the price. If freedom is truly desired, blood must be spilled.
With the old USSR, it took decades of bleeding, which continues today in East Ukraine.
By nature, humans hate change. With this in mind, will the Middle East change any time soon? Will Russia? Will we?
