(CNN) President Donald Trump took credit Thursday for recently renewed communications between North Korea and South Korea.

"With all of the failed 'experts' weighing in, does anybody really believe that talks and dialogue would be going on between North and South Korea right now if I wasn't firm, strong and willing to commit our total 'might' against the North," Trump tweeted Thursday morning.

He added, "Fools, but talks are a good thing!"
