No One Left To Conquer

 The recent unrest in the Middle East and North Africa should have been expected.
When a population outgrows the limits of it's traditional institutions - new institutions must take over.
But these countries may be better off than us.
Most don't have the technology to destroy themselves on the same scale as America processes.
Judging by our avarice - maybe our American society has reached it's peak in it's value to mankind.

 Like other countries, cultures, and societies before us - maybe we are doomed to repeat the cycles of the past.
Without a change in values, morality (not necessarily those of Christian churches), and consciousness - maybe we have just come to the end of our part in the evolutionary cycle.

Maybe Revelations (and Charlton Heston) was telling the truth.
