September 11 has become increasingly meaningful as each year passes.  In 2001, that day shattered a notion that the United States of America was immune from foreign terrorists.

In 2012, it was also a day that Ambassador Chris Stevens, Information Officer Sean Smith, and former U.S. Navy SEALs Tyrone Woods and Glen Doherty were killed in an attack on the U.S Consulate and Annex in Benghazi, Libya.

Let’s also bring up another interesting span of time that involves a red line.  August 20, 2012 during a press conference, President Barack Obama was asked about whether military action by the U.S. was needed in Syria.

“…We have been very clear to the Assad regime, but also to other players on the ground, that a red line for us is we start seeing a whole bunch of chemical weapons moving around or being utilized.  That would change my calculus.”

August 21, 2013 chemical weapons were used in Syria and over a thousand people were killed.  Thus the red line is crossed and until recently, it seemed retaliation against the Assad regime was certain.

It would be ludicrous to equate the deaths of four Americans in Benghazi to the thousands of dead in Syria.  Nonetheless it would behoove Americans to be vigilant in demanding justice for the attackers in Libya.  Killing an American Ambassador crosses some kind of line, red or otherwise.
