San Bernardino, Calif among many others most of which the attackers were heard to yell “Allah Akbar” which would indicate they were at least Isis inspired.

If Isis wasn't around they can't inspire anyone and yes I know others will take their place but allowing them to grow unfettered gives them the ability to expand their influence beyond their borders and create havoc around the world. Maybe if they were denied electricity in their areas they would not be able to communicate so easily. Our administration and the mainstream media are trying to play down these attacks by trying to imply they are home grown terrorist attacks or some such bull shit. If Isis is left alone there will be a very major terrorist attack in our future in this country and possibility elsewhere in the world as well.
