Republican presidential candidate Dr. Ben Carson says the United States should formally declare war on ISIS, which would allow the government to treat U.S. citizens who aid and abet ISIS as traitors.
"We need to recognize that we are at war," Carson told NewsMaxTV on Thursday. "This is nothing to play around with, and also, once that formal declaration of war has been declared, anybody aiding and abetting them will be a traitor and will be treated as such and I think that makes a big difference."
Once leading the Republican field in certain polls, Carson's campaign suffered as the national debate turned towards foreign policy after the terror attacks in Paris and San Bernardino.
In the interview, Carson said executions of traitors should not be taken off the table.
"I think that certainly is not something that I would take off the table, doesn't say that you have to execute them it says that it is one of the tools that is available to us," he said.
