Pew research conducted a survey in 39 countries with 38,000 Muslims on tpics like honor killings, suicide bombings, and sharia law. With all of the polls in consideration they found that 680 million Muslims are radical out of a total of 1.6 billion. They didn't get to poll every country though. Nearly half of Muslims are radical. That's a lot more than the minute minority the left talks about. Read the article for the full story.

Sebastian Gorka speaks about this often. He believes that most Muslims probably wouldn't support the jihadist faction (Salafist/Twelver) if they were losing. But the perception, largely driven by the diffident, girlish passivity of the Eightball Obama's regime, has given the greater impression around the world that the militant fundie muzz are winning.
That impression (according to Dr. Gorka) needs to be countered by a multi-pronged assault which consists of killing terrorists in their areas of operation, rooting out / decimating their funding, calling them out by name (referring to them as militant fundamentalist Islamist terrorists), promoting an effective media campaign to demonstrate that being a terrorist is a means to achieve nothing but an early agonizing death and to support sheikist (non-militant, Western-friendly) Muslim governments in their own internal struggles to defeat radical Islam.
There is a lot of evidence that appointing Dr. Gorka to lead the policy/strategy of the White House staff in the anti-terrorism effort was one of the smartest things that President Trump has done.
The amount of progress that has been made against radical Islamist terrorist networks in only the first half of the first year of the administration is a major triumph. Hundreds of thousands of muzz terrorists have been killed, vast swaths of territory have been retaken from ISIS/al Qaeda/Taliban etc., and international cooperation in WW"T" is at a very high level and increasing every day.
