What accounts for the lack of a CVE strategy in the USA?

Over the last few years the United States has been one of the most enthusiastic proponents of the introduction of Countering Violent Extremism (CVE) activities worldwide. It has spearheaded countless global initiatives, from a high-profile global summit hosted by the White House in February 2015 to the formation of permanent CVE-focused initiatives like the Abu Dhabi-based Hedayah. It has also been providing substantial financial support to counter-radicalisation programmes implemented in countries throughout the world through various State Department or USAID-funded initiatives.
