United States President, Donald Trump has in a not too surprising twist, canceled the planned June 12 summit in Singapore with North Korea’s leader, Kim Jong Un. Trump cited “tremendous anger and open hostility” as reasons, in a recent statement from North Korea.

It is coming on a day that North Korea supposedly dismantled its nuclear bomb testing site, in the presence of some invited journalists. President Trump said in a letter to Kim released on Thursday by the White House that based on the statement, he felt it was “inappropriate, at this time, to have this long-planned meeting.”

The president says the North Koreans talk about their nuclear capabilities, “but ours are so massive and powerful that I pray to God they will never have to be used.”
