Three nations led the attack against Libya's leader Gaddhafi. They supported the jihadist inspired insurgency against the Libyan government by bombing any Libyan military target they could find.
Britain and France trained for this intervention in the Southern Mistral 2011 maneuver which was eventually merged into the real war on Libya. The U.S. joined in on the campaign by providing the "break in" capability that defeated the Libyan air defense network.
The hope of all three nations was to increase their diplomatic leverage and economic advantages by installing a friendly puppet government in Libya.
Since then all three nations had to learn that there diplomats are not welcome in Libya.
On July 11 2012 the British ambassador convoy was attacked in Benghazi. The ambassador escaped the assassination attempt but two man of his protection detail were wounded.
On September 11 an attack on a U.S. "consulate" that was a cover for a large CIA station killed the U.S. ambassador to Libya.
Today a car bomb exploded in front of the French embassy in Tripoli and wounded two of the embassy security detail as well as a Libyan civilian.
The three nations that intevened all had their diplomats attacked by very same jihadist insurgents they "helped" to take over the country.
One would hope that politicians would learn a bit or two from such blowbacks. Unfortunately that is not the case. The same three key countries are now supporting the jihadist insurgency against the Syrian government. The only thing that will prevent similar blowbacks is a victory of the Syrian government over the insurgency, something that still looks likely.
