Here’s more evidence that the answer is No. The terrorists may be culturally Muslim, but like the vast majority of terrorists–Irish, Tamil, Palestinian, Basque, Syrian, etc.–they are motivated by foreign oppression of their people, not by religion. Are they especially evil, as versus their opponents, to strike at civilians? That is always murder. It’s also the typical tactic of Western governments. Is directly shooting people worse than setting off Hellfire missiles from a cozy basement in Nevada? Of course not; it is all evil.
“Blessed are the peacemakers, for they shall be called the sons of God.” And peacemaking is the only way to diminish and eventually eliminate terrorism. For example, getting out of all Muslim lands. When people are willing to die in their warfare, there is no way to stop them. Our only hope is to treat them as we wish to be treated.
