President Trump made a “pretty significant concession” to North Korea by agreeing to end joint military exercises with South Korea during his summit with North Korean leader Kim Jong Un, former CIA Director Michael Hayden said on Tuesday.

“The president obviously made a judgment that he needs that concession in order to keep this process moving forward,” Hayden told CNN. “But that is the only concession that was made in yesterday’s talks. The North Koreans did not come with anything new. The new element is that we agreed to stop our annual exercise cycle with our South Korean allies. That’s actually a pretty significant concession.”
