It's a very impressive piece of work you've done. Just one grammatical tip: the word "begun" in English is the past participle of the verb "to begin", so it has to be preceded by an auxiliary verb like "had", "has", etc. For example, before the terror began, before the terror had begun, before the terror will begin again, etc. I have a feeling there will be alot of pressure on you to pull this item, especially in view of the new anti-American nationalism in Germany. So there may be some controversy ahead. But don't let it discourage you from continuing your fine modelling work.
