The President of the United States has called for a “secret travel service” to be set up to protect Americans from terrorists in the event of a nuclear attack.

The plan is being drafted by John McCain and Lindsey Graham, along with the Republican Senator from South Carolina.

“It’s been a very challenging time for Americans, but in the end, this is what we need to do,” President Barack Obama said on CBS’s Face the Nation, as quoted by The Washington Post.

Obama said that in the unlikely event that the United Nations Security Council did decide to sanction North Korea, the travel service would be tasked with providing information to the public on any such sanction.

He said that the plan would be “very, very carefully crafted.”

“There is no doubt that if North Korea is going to conduct an attack on us, we will have to be prepared, because if they are capable of launching nuclear weapons, then they will certainly be able to do that,” Obama said.

Graham, McCain and Senator Lindsey Graham are calling for a secret travel service, as well as a plan to counter cyberattacks. 

In the event that North Korea conducts an attack against us, it would be a very, very difficult decision for us to have to put up a security system that would prevent that attack from happening.

Graham said. 

“If North Korea were to go through with an attack, then I believe that the travel system could provide information to us on any possible sanction, including any threat of a preemptive nuclear strike,” Graham said in an interview with The Washington Examiner. 

McCain said the secret travel system would be set-up “so that people around the world have a way to report what is going on with the travel of North Koreans to the United Kingdom.”

“There are ways to tell them,” McCain added.

The Senate is expected to vote this week on legislation that would allow North Korea to be sanctioned for using nuclear weapons.

North Korea has threatened to attack the United State and the world with nuclear weapons during its two-month long state of war with South Korea.
