"Our organized forces are small, the enemy's forces are huge. We live inside the oppressor nation, particularly suited to urban guerilla warfare. We are strategically situated in the nerve centers of the international empire, where the institutions and symbols of imperial power are concentrated. The cities will be a major battleground, for the overwheliming majority of people live in the cities; the cities are our terrain."
