Glasgow: America under Donald Trump would come to Australia's aid in a crisis, despite the remarkable events of the past week, Defence Minister Marise Payne has said.

Ms Payne says that she is confident that Australia's defence alliance with the US is as strong as ever and while President Trump "thought outside the square box” that doesn't put Australia's national security at risk.

The Minister was in Brussels last week where Mr Trump demanded that NATO allies double – even quadruple - their defence spending, reportedly threatening to pull US troops out of Europe and “go it alone” if they didn’t.

He later claimed to have won new unspecified commitments for more and faster defence spending, and declared NATO was stronger than ever.
