US versus Russian bombing of ISIS targets

"In the aftermath of the attacks in Paris this month, the United States has more aggressively targeted the militants’ oil production and smuggling operations, which it had held off from doing for fear of inflicting long-term damage to the Iraqi and Syrian economies. American aircraft this month struck a convoy of oil tanker trucks in eastern Syria, destroying 116 vehicles."  Russia in the same week announced that it destroyed more than 400 vehicles but that does not make it into US media.
