you are adding new elements to the definition, but fine i'll roll with that, except for iran no country has had islam changed its political situations, on the other hand theres countless example of israle/us/uk engaging in regular, global, overt and covert(terrorist) operations to topple governments and change political spectrum in a country.
I dont think you are approaching this in an academic manner, had you said i dont think the 2 cultures(west and islam) are not compatible, i could accept that point of view but to say that terrorism is in inherent in islam is simply ignorant imo
