Al Qaeda's number 2 leader mocked President-elect Obama on a web broadcast citing a "heavy legacy and crimes await" him.
Ayman al-Zawahiri criticized Obama's foreign policy on Israel, Afghanistan and Iraq, comparing him unfavorably to 1950's and 60's activist Malcom X.
There are videos of messages including speeches from Malcom X in the taped broadcast.
The speaker says that Obama's plan to pull troops from Iraq and send them to Afghanistan "is a policy that is destined for failure before it was born."
The message says Obama is the direct opposite of honorable Americans like Malcom X. The speaker says that Obama and former and current Secretaries of State Colin Powell and Condoleezza Rice fit the description of "house slaves", a term Malcom X used to describe African Americans who were subservient to whites.
The message reiterated the call to fight Western powers in the Middle East and to be "firm and resolute". The speaker says the enemy has begun to stagger so keep hitting him.
