During his speech, McCain argued Australia should not forsake its alliance with the United States now that the Trump administration is in the White House.

“There is real debate underway now in my country about what kind of role America should play in the world and, frankly, I don’t know how this debate will play out,” McCain, a frequent critic of the president, reportedly said in his address.

“But I do believe — and I don’t think I'm exaggerating here — that the future of the world will turn to a large extent on how this debate in America is resolved. That’s why I and others are fighting so hard to ensure that America stands by our allies and remains an active, principled leader in the world.’’

McCain on his trip met with top Australian defense and foreign affairs officials.

His comments follow Trump's first overseas trip as president, after which German Chancellor Angela Merkel said the European nation can no longer "completely depend" on the U.S. as a partner.
