Democratic President Barack Obama should, for once, “lead from behind” and follow the example of British Prime Minster David Cameron in “calling a spade a spade” by explicitly identifying radical Islam as the enemy of the United States, Gov. Bobby Jindal says in an opinion piece published by Conservative Review.

Obama’s failure to invoke the phrase endangers U.S. security, Jindal wrote. Obama has said he avoids associating jihadist terrorists with Islam because he doesn’t want to confer religious legitimacy on them.

The charge is nothing new for Jindal. Nor is his call in the piece for the nation to close its borders to would-be immigrants who refuse to embrace American values.

Conservative Review is a right-leaning media outlet that tabulates ideological scorecards on members of Congress and presidential candidates — including Jindal, who is seeking the 2016 Republican nomination to the White House.
