Whether the desired response was immediate large scale government reform, or violent revolution resulting in a new government (and his statements leave room for either) is debatable. Certainly the means and target were unconscionable; we can debate whether the 911 hijackers had legitimate grievances with US CEOs, but the more likely any such execs were to be guilty of any wrongdoing, the less likely they were to be at the World Trade Center 0830 Tuesday morning. But, yes, I have to say it was an act of violent intimidation by terror, motivated by his belief system as well as his personal history. It was terrorism, not religiously motivated, but Trotskys terrorism wasn't religious, nor Ben Gurions; it was still terrorism. He wasn't even after specific people, just IRS employees in general, the vast majority of whom were just working stiffs trying to feed their families, just like him. It was terrorism, plain and simple.
