Dr. Ayman al Zawahiri explains;

“The strength of Al Qaeda, with the blessing and might of Allah, is neither its numbers nor arsenal; for that cannot be compared with the resources, equipment and numbers of western empire of evil.

Rather the strength of Al Qaeda, with the blessing of Allah, lies in its message for the Muslim Ummah and the oppressed of this world. It lies in its message to rise in the face of this system of global oppression, international arrogance and worldwide theft. The strength of Al Qaeda lies in its message to revolt against this system of polytheism that worship matter, power, interest and luxury. It lies in its call to rise against this satanic system of international legtimacy that aids the executer against the executed, murderer against the murdered and the thief against the victim of theft”
