Reality: I think your definition of terrorism is a bit vague. You say that it is "the use of violence for coercive political means" (don't you mean political "ends", not means?).
When the Allies invaded France to drive the Wehrmacht out, and eventually installed, against the will of the German people, a new replacement government for the Hitler regime which we had overthrown ... was this terrorism? We coerced the German nation, and we used violence to do so. I would classify some of this violence as "terrorist" --deliberate attacks against civilians -- but not most of it: for instance, bombarding the German army.
Also: "coercive political [ends]" should be clarified: it is not clear, to me at least, what you mean here. Could you give some examples, and some non-examples?
Firstly, thank you for a well thought out and polite post.
On "means" i think that is the appropriate word. Terrorism is a means to an end, per say. To use Palestinian terrorism as an example, they don't blow up people because they are rabid antisemites, as some would have us believe. They blow up people to terrorize the wider population into subjugating to their ideal (these groups vary widely on ends, some the destruction of Israel, some a state, end of occupation, etc.)
I think there are comparisons to the bombing of Berlin. Granted, the technology did not exist for what we have come to know as strategic targeting, but lets also not pretend that bombing civilians into submission was an unwelcome sidebar. Sure, destruction of the regime was the goal, but subjugating the population into rejecting the regime was more than welcome.
I tend to define terrorism broadly, as it would be defined in a dictionary. Merriam-Webster defines terrorism as "the systematic use of terror especially as a means of coercion."
I think another valid example is the "Shock and Awe" campaign which launched the invasion of Iraq. Its stated goal was to show American force, mostly on Baghdad. A Pentagon strategist told CBS before the war began that "there would be no safe place in Baghdad." Baghdad had, at the time, some 5m people. Clearly, pounding the Iraqi populace into turning against the regime certainly falls under the terrorism definition. To me, another obvious parallel would be Hiroshima and Nagasaki.
Many people get upset when i draw these parallels, calling me anti-American and bla bla bla. In actuality, it is not that I try to make Americans "terrorists." It is my position that terrorism is a natural tactic in war, similar to the use of propaganda. Terrorism is a natural occurrence in conflict.
It is not terrorism, per say, that I am speaking against. It is the stupidity of a "war on terror." There is no war on terror. Terrorism has been used in every conflict in modern times by every side. It is nothing more than violent propaganda.
I think the use of the phrase "war on terror" really just dumbs down the discussion we all need to be having. These are not "depraved opponents of civilization" as Reagan called them, they do not "hate us for our freedoms" and we are not in a "battle against evil." We are being opposed for our actions or their interpretations of our actions. Their interpretations is something we should all work a lot harder to understand, instead of wasting our time with misnomers fit for a Star Wars movie.
