Retired four-star Gen. Jack Keane said Tuesday that President Trump's proposed second summit with North Korean leader Kim Jong Un cannot be a repeat of their first meeting.

Keane, a Fox News senior strategic analyst, said that "deliverables" need to be a product of the prospective meeting. 

Secretary of State Mike Pompeo told Fox News last week that the next summit between the two leaders will take place by the end of the month.

Keane said on America's Newsroom that it's likely Trump will announce the location of the meeting during his State of the Union address Tuesday night.

"They have to have some deliverables at this summit for it to be successful," he said, adding that he doesn't think the U.S. will ease its sanctions on North Korea.

Keane's remarks come amid reports that North Korea is working to ensure its missile are protected from potential U.S. military strikes.

"If they're willing to make some concessions to us about the inventory of their weapons systems, a program and a timetable to eliminate them with independent inspectors to verify ... that would really be some progress," he said.

Keane said one deliverable to come from the next Trump-Kim summit would be to formally end the Korean War.

"They have to make some significant concession to us, and other than them stopping testing of missiles and nuclear weapons there has been no progress made on the core issue which is disarming nuclear weapons and ballistic missiles," he said.
