With financial aid from wealthy American bankers, the tyrannical tsar of Russia was overthrown by the infinitely more tyrannical Communists. In Cuba, President Batista was no angel, but the Communist revolution, supported by the American left, was infinitely more evil. The Shah of Iran had his faults, but his overthrow, supported by President Jimmy Carter, put the Ayatollah Khomeini in power and led to the troubles in the Muslim world today. Etc., etc. Get the picture?
Now would-be dictator President Obama and his radical allies propose a bloody war to depose the government of Syria, which will lead to a government by insurgent terrorists allied with al-Qaeda and risk leading us into World War III. Déjà vu.
