Biggest Threats to US Include Homegrown Terror, North Korea, Intel Chiefs Say

Top intelligence officials laid out the threats in a senate hearing.

Here are some of the highlights:

Terrorism in the US: Stewart cautioned against homegrown threats, saying, "ISIL will probably attempt to conduct additional attacks in Europe, and attempt to direct attacks on the U.S. homeland in 2016." In his written statement, Clapper similarly warned that “the perceived success of attacks by homegrown violent extremists in Europe and North America, such as those in Chattanooga and San Bernardino, might motivate others to replicate opportunistic attacks with little or no warning, diminishing our ability to detect terrorist operational planning and readiness.” He said that U.S.-based homegrown violent extremists pose "the most significant Sunni terrorist threat to the US homeland in 2016."

Taking Back Mosul: Stewart said he was not optimistic about taking Mosul from ISIS in the near term, saying it's unlike to happen in the next year. "We may be able to begin the campaign, do some isolation operations around Mosul," he said. "But securing or taking Mosul is an extensive operation and not something I see in the next year or so." Stewart also mentioned there is still work to be done to secure Ramadi.
