Of course they have the ISIS part wrong, but the general idea is correct... Terrorism works when you react to it... that is the POINT of Terrorism, rather than of simply armed conflict.
In WWII the German V2 rockets included noise generators that made a loud wailing sound. This was to create fear, or a feeling of Terror. The psychological damage multiplied the physical damage.
Reacting to Terrorism is the surest way to give it power. The existence of the TSA is the end result of the Terrorism of 9/11 - regardless who was the cause, the reaction has had a profound impact on life in the US for several generations later.
