It boggles the mind

According to Fox News, fuel trucks and convoys of ISIS were previously "off limits" to U.S. attacks.  Lessee....we have an enemy that uses mechanization to go across large expanses of land to attack innocents, and we had to let over a hundred people die in Paris before we could even go after their fuel trucks and oil refineries? 

Seriously?  When a huge part of winning the Civil War, World War One, and World War Two was due to effective blockades of the enemy, we couldn't even go after the supplies of ISIS?
