>> President Donald Trump struck a triumphant tone on his return to Washington Wednesday after his summit with Kim Jong-un. Trump tweeting, there is no longer a nuclear threat from North Korea. Adding, everybody can now feel much safer than the day I took office. In fact, North Korea has not given up or dismantled its nuclear arsenal, but only promised to denuclearize, without specifics on when or how.
Trump's allies on Capitol Hill offered cautious praise.>> The path we were on was not working. The president should be applauded for disrupting the status quo. Now, let's go get an agreement. And we have to make sure that we have irreversible, comprehensive denuclearization of North Korea.>> Foreign policy editor, Mary Millican.
>> A growing number of Republicans are saying it's good that the United States is talking to North Korea, but let's not let up in our maximum pressure campaign, and let's not trust them too much.>> The vagueness of the pact Trump and Kim signed taking flack on Capitol Hill.
>> There's nothing in the documents that were signed that would indicate that North Korea is no longer a nuclear threat.>> And Trump's Republican allies also seemed confused about his pledge to end, quote, war games with South Korea.>>
> On Wednesday, North Korean state media hailed the war games agreement as a major concession by the US.
Millican says despite all the confusion, Reuters polling shows the summit appears to be popular with Americans.>> So while 51% of Americans approve of President Trump's handling of North Korea, only a quarter, 26%, believe that what happened at the Singapore summit and the pledges that the two leaders made in their joint declaration will actually lead to the denuclearization of the Korean Peninsula.
>> Experts say the process of denuclearizing the Korean Peninsula will actually be long and difficult, even if it begins immediately. Secretary of State Mike Pompeo, in South Korea for post-summit talks, said Trump would like to see major North Korean nuclear disarmament over the next two and a half years.
