I am sure ISIS and al Qaeda feel they are being terrorized and Americans fully support these operations. Pakistan and Yemen help with these missions because they want them eradicated. Europeans criticize while not realizing these operation are run in large part from Europe. As long as the governments of Europe do what the U.S. says the opinion of their citizens can be ignored.
Redefining 'civilian' also reduces civilian casualties.
"It is also because Mr. Obama embraced a disputed method for counting civilian casualties that did little to box him in. It in effect counts all military-age males in a strike zone as combatants, according to several administration officials, unless there is explicit intelligence posthumously proving them innocent."
I don't imagine anyone cares to do the posthumous intelligence checks.
