Sorry to say; as I do not know you as a person, but the whole retaliation-like ideology is foolish.
Two (or more) wrongs NEVER make anything right; just worse. Words to live by. Doing the RIGHT thing is always the best thing and there is never any excuse or justification for doing otherwise regardless of what you think. Terrorism, regardless how slight, the commission of a crime to purportedly out others that have ideals, morals, politics or business models, etc that you do not agree with or to in fact to out ones wrongdoings, is still 1000% wrong; just due to the nature of the methods you go about to perform such tasks.
And that's all it is, an over simplistic, childish excuse to justify wrongdoing. Just like those you claim to hate; you too are doing the SAME things, just on the other side of the fence. And it is NEVER good to defend ANY terrorist; foreign or domestic; large or small; or anything in between.
