Maybe modern terrorism, there were terrorists in the middle east going back to biblical times.
Lenin definitely used and endorsed terrorist methods. He wrote once, "In principle we have never rejected, and cannot reject terror. Terror is one of the forms of military action that may ..be perfectly suitable and even essential at a definite juncture in the battle, given a definite state of the troops and the existence of definite conditions."
But what bothers me most about the return of Lenin to Russia is that they are back on the track of Marxist imperialism: not content with fixing their own internal mess, they want to export that mess to the rest of the world. They would like to see little Saddam regimes running the whole world.
