'Clinton, Bush and Obama all failed with North Korea, I won't fail' - Donald Trump

President Trump is still tweeting about North Korea and its leader saying negotiating with them hasn't worked in 25 years, why will it work now. He then went on to say 3 presidents before him failed on the North Korea issue but he won't fail.

I told Rex Tillerson, our wonderful Secretary of State, that he is wasting his time trying to negotiate with Little Rocket Man...

Being nice to Rocket Man hasn't worked in 25 years, why would it work now? Clinton failed, Bush failed, and Obama failed. I won't fail.
