CNN reports that In hundreds of highly classified phone calls with foreign heads of state, Trump was so consistently unprepared for discussion of serious issues, so often outplayed in his conversations with powerful leaders like Russian President Vladimir Putin and Turkish President Recep Erdogan, and so abusive to leaders of America’s principal allies, that the calls helped convince some senior US officials — including his former secretaries of state and defense, two national security advisers and his longest-serving chief of staff — that the President himself posed a danger to the national security of the United States, according to White House and intelligence officials intimately familiar with the contents of the conversations.

The calls caused former top Trump deputies — including national security advisers H.R. McMaster and John Bolton, Defense Secretary James Mattis, Secretary of State Rex Tillerson, and White House chief of staff John Kelly, as well as intelligence officials — to conclude that the President was often “delusional,” as two sources put it, in his dealings with foreign leaders.

These officials’ concerns about the calls, and particularly Trump’s deference to Putin, take on new resonance with reports the President appears to have learned in March that Russia had offered the Taliban bounties to kill US troops in Afghanistan — and yet took no action.

Trump also regularly bullied and demeaned the leaders of America’s principal allies, especially two women: telling Prime Minister Theresa May of the United Kingdom she was weak and lacked courage; and telling German Chancellor Angela Merkel that she was “stupid.”

Trump incessantly boasted to his fellow heads of state, including Saudi Arabia’s autocratic royal heir Mohammed bin Salman and North Korean dictator Kim Jong Un, about his own wealth, genius, “great” accomplishments as President, and the “idiocy” of his Oval Office predecessors, according to the sources.

Like Bolton, CNN’s sources said that Trump seemed to continually conflate his own personal interests — especially for purposes of re-election and revenge against perceived critics and political enemies — with the national interest.

One person familiar with almost all the conversations with the leaders of Russia, Turkey, Canada, Australia and western Europe described the calls cumulatively as ‘abominations’ so grievous to US national security interests that if members of Congress heard from witnesses to the actual conversations or read the texts and contemporaneous notes, even many senior Republican members would no longer be able to retain confidence in the President.
