History Repeats Itself and Repeats Itself And. . .

Here we go again:

Fifty U.S. Marines were headed to Haiti on Monday to protect the American Embassy and diplomats after rebels overran Haiti’s second-largest city and began detaining supporters of President Jean-Bertrand Aristide.

Western diplomats, speaking on condition of anonymity, said the Marines were requested after rebels threatened to attack the capital, Port-au-Prince, soon.

How many times is that now we’ve had to send in the Marines to Haiti?
