Earlier quoted context omitted.
While we can debate the level to which America needs to get involved, are you forgetting 911 or any of the other terrorist attacks? It honestly feels downright insulting to the victims of terrorism that you would imply these extremist groups do not threaten your freedom. The article specifically references that these devices used on members of aal-Qaida; the group responsible for 911.
The war on terror has killed easily three orders of magnitude more people than 9/11, and antagonizes the US with the regional population. It's neither proportional nor effective.
My point was the OP said "these people do not pose a threat to my freedom" which is categorically false. Aal-Qaida is a terrorist group that directly caused the deaths of thousands of Americans, ripping them from their loved ones. To make _this specific argument_ against this weapon is just insulting to the victims.
