"Tragedy" is an inaccurate word, as Atlas Shrugs and Donald Sensing point out. It was an act of war and it was an atrocity. It was not a tragedy for its victims; it was a field of courage and heroism for them and their rescuerers. It was not a tragedy for Nasan; he planned it as a Jihadist suicide mission and will probably be disappointed when (if) he awakens from his coma to discover he is not in Allah's heaven with 72 raisins.
America 's homeland has been under Jihadist attack since the 1993 bombings of the World Trade Center in New York. We've had numerous terrorist conspiracies discovered and thwarted, we've had some botched terrorist attempts, we've had Muslim anti-semitic attacks on Jews and synagogues, we've had brief shootouts between Islamists and police, we've had a horrendous serial killing spree around the nation's capital that took days to end. We're way past the moment when the nation was innocently asleep and horrifyingly awakened by Muslim mass murderers shouting "Allahu Akbar" and flying airplanes into buildings. It's not a tragedy that we are unprepared now; it's political correctness stupidity, it's political cowardice, it's personal irresponsibility, it's professional incompetence.
