The US is sending 50 Marines down to Port Au Prince to protect the embassy in the event that the rebels capture the capital city. Don’t expect folks to forget that it was the USA that put Aristide back in power in 1994 after these same folks (or at least many of the same people) threw him out.
I hope that the incoming government, whatever that looks like, has more to their 5-year plan than just ousting Aristide.
