why did it take so long for the U.S. or any of the coalition forces to bomb the oil truck convoys? Also, why did the U.S. warn the drivers in that convoy to leave their trucks? I thought we wanted to kill ISIS. So what's up with that?
The truck drivers are not members of Islamic State. The truck drivers are ordinary civilians who are just trying to survive in a war zone.
We did not bomb the trucks at first because we wanted to avoid the deaths of innocent truck drivers.
After the Paris attacks, we decided that we would have to go ahead and risk killing the truck drivers in order to have a greater impact on Islamic State.
However, we still do not want to kill innocent truck drivers, so we try to give them as much of a chance to escape as possible while still destroying the oil shipments.
It's the way war is fought by countries that do not target civilians.
