"No weakening of resolve" by US towards NATO under Trump: Obama

US President Barack Obama has said that Washington would remain the world's "indispensable" power and committed to NATO even under the administration of his newly-elected successor Donald Trump as the latter has assured him about the same.

"In my conversations with the President-elect, he expressed a great interest in maintaining our core strategic relationships," Obama said, adding that he had a message from Trump to pass on to world leaders he will meet this week. "One of the messages I will be able to deliver is his commitment to NATO and the transatlantic alliance," said the President.

President Obama will be reassuring the same to US allies during his overseas trip this week.

Obama added, "There is no weakening of resolve when it comes to maintaining a strong and robust NATO relationship."

The President made the remarks in a news conference on Monday, his first since last week's stunning election results, before leaving the United States on the last scheduled foreign trip of his presidency to Greece, Germany and Peru, reports the CNN.

Obama also said he was certain after meeting Trump last week that his successor and longtime political foe was "sincere" about being the President for all Americans but also called on the President-elect to reach out to people who felt anxious after the explosive rhetoric of the campaign, including women and minorities.

"I don't think he is ideological, I think ultimately he is pragmatic in that way and that can serve him well as long as he has got good people around him and he has a good sense of direction," Obama said.
