The question then becomes why were the bombings not getting as much or more coverage than a temporary visa ban?
5 of the 7 countries on the visa list are currently being bombed by the US [0].
It's no surprise then that these countries made it on to the Obama administration's list of countries that are sources of terror, which was used as the basis for Trump's visa ban.
From a security perspective it's difficult to argue that countries you are currently bombing won't have people trying to enter the U.S. looking for payback.
