Authoritarian $y$tems always label their opponents and their victims by some sort of nasty name...communist, terrorist, Jew, traitor, Gypsy, renegade, pagan, apostate, heretic, nigger-lover, etc...

The name camouflages the real facts of the matter.

And the oppressors change hats as history rolls along. Former victims easily assume the mantle of future oppressors, once they get on top.

Look for who has the most guns, the most money, the most propaganda, and the greatest ability to destroy...and THERE you will find your number 1 terrorists. Terrorism is: the deliberate terrorizing and killing of people in order to gain greater material wealth and worldly power.

It has been practiced by every powerful government in the history of the World at one time or another. It is being practiced right now by the USA and Great Britain and Israel. It results, naturally, in smaller and less well organized terrorism in response by those who are being invaded and massacred, so you have terrorism happening on both sides.

Nothing new about that. In any long war you will find terrorism being practiced on both sides. Each side will hypocritically accuse the other of terrorism while turning a blind eye to its own.

The only ones who are not supporting terrorism are the ones who are not willing, like Adolf Eichmann, to simply "follow orders" and kill people. That takes courage. Killing people just takes a gigantic lack of imagination, empathy, and awareness.
