AMMAN, Jordan – The Obama administration’s diplomatic point man in the fight against the Islamic State group said Sunday the extremists have been losing control over territory and that “this perverse caliphate is shrinking.”

Brett McGurk, presidential envoy to a 66-member anti-IS coalition, also told a news conference the tide has turned in the ideological battle against the extremists.

He described a round-the-clock anti-IS propaganda campaign involving companies such as Facebook and YouTube and the governments of Jordan, Malaysia and the United Arab Emirates.

“For every pro-Daesh Twitter handle, there are now six calling out its lies and countering its message,” McGurk said, referring to IS by its Arabic acronym.

U.S. officials said earlier this year that the military had ramped up cyber operations against the group.

The officials said at the time that operations include efforts by U.S. Cyber Command at Fort Meade, Maryland, to prevent the group from using the Internet and social media to communicate and distribute propaganda aimed at attracting and inspiring recruits.

In his news conference, McGurk singled out Jordan as an example of what he called Washington’s “sustainable strategy” of eschewing boots on the ground for local, regional and Islamic forces against IS.

He said Jordan has been conducting weekly airstrikes against IS targets and is involved in intelligence gathering and anti-IS propaganda.

Islamic State has suffered recent military setbacks and lost territory in Iraq and Syria.

But as Islamic State militants are pushed back along front lines, the group is increasingly turning to insurgency-style terrorist attacks to keep pressure on the Iraqi government. Such attacks have left more than 100 dead in the past week.

While IS is losing ground in Iraq and Syria, its global affiliates appear to have grown in strength in countries like Libya.
