WASHINGTON (AP) — President Donald Trump is canceling the planned June 12 summit with North Korea’s Kim Jong Un, citing the “tremendous anger and open hostility” in a recent statement from North Korea.Trump says in a letter to Kim released 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.”

But in a statement, the North Korean government had referred to Vice President Mike Pence as a “political dummy” and said it is just as ready to meet in a nuclear confrontation as at the negotiating table.

But Trump tells Kim “please do not hesitate to call me or write” should he change his mind about a one-on-one meeting.

Trump says the U.S. military is “ready if necessary” to respond to “foolish or reckless acts” by North Korea.

Trump also says he’s been in touch with South Korea and Japan and that both allies are willing to bear much of the financial burden “if such an unfortunate situation is forced upon us.”
