If there really were four hundred surface to air missiles in Benghazi that fell into the hands of terrorists, it matters. If Benghazi was being used as a transit hub for weapons flowing to Syria, it makes a difference.
If the Obama Administration was sending sophisticated surface to air missiles to the Syrian rebels, without congressional authorization, it matters a lot.
If Islamist terrorists are in possession of American surface to air missiles, this becomes a scandal that makes all other previous scandals pale in comparison.
No one died in Watergate or Iran Contra. No one died in White Water.
If it is true that we shipped surface to air missiles to Benghazi and then they fell into the hands of terrorists, we face one of the worst threats we have ever faced. We face the prospect of something that could dwarf 9/11. We face the prospect of unconventional war on American shores.
