Plenty of pundits are advising the Israelis to avoid following the 9/11 precedent, where we allegedly overreacted out of anger without fully considering the consequences of our actions. Is the analogy correct?
Not exactly. The part about not fully considering the consequences of our actions is correct, but the part about blind anger is not. The Afghanistan military campaign was justified and limited in scope; it was what happened with nation-building in the 20 years thereafter that was the mistake. The Iraq War was not a reflex; it was a cold-blooded effort to carry out the George W. Bush agenda for the Middle East. It started long after 9/11. If you consider it a crime, it was premeditated murder, not an unjustified emotional overreaction that would qualify as second degree murder.
