Al Qaeda's second-in-command, Ayman al-Zawahiri, taunted President Bush in a new video released Monday, ridiculing his new Iraq policy and daring the U.S. to "send the entire American Army" to Iraq.

“Why send 20,000 only, why not send 50 or 100 thousand?" al-Zawahiri asks in a video intercepted by SITE Institute. "Aren't you aware that the dogs of Iraq are pining for your troops' dead bodies?”

According to SITE Institute, the 14-minute speech titled “The Correct Equation” was produced by the Al Qaeda's media arm as-Sahab, and was set to be posted on Islamic militant Web sites.

In the message, which includes English subtitles, al-Zawahiri calls on President Bush to send the entire American Army to Iraq, saying the Mujahadeen (warriors engaged in jihad) are capable of destroying the equivalent of 10 armies.

Al-Zawahiri warns that peace is impossible if Americans continue to follow Bush's policies.

“If we are secure, you might be secure; and if we are safe, you might be safe," al-Zawahiri says. "And if we are struck and killed, you will definitely — with Allah's permission — be struck and killed.”

Much of the speech is dedicated to inciting Muslims, urging them to join the jihad or at least to support those conducting jihad in war zones such as Afghanistan, Iraq, Palestine, Chechnya, Somalia, and Algeria.
