While in Australia, U.S. Sen. John McCain warned that Russia is a bigger threat to global security than ISIS. He made the comment on his way to a defense summit in Singapore.

As head of the Senate Armed Services Committee, the McCain spent much of his visit calming our allies. He urged Australia’s leaders on Tuesday not to abandon its alliance with America despite jitters over President Trump.

Trump’s relationship with Australia started poorly at the onset of his presidency when he announced his decision to pull out of the Trans-Pacific Partnership trade pact.

Trust continued to erode this week with revelations that Trump’s son-in-law, Jared Kushner, may have colluded to establish a secret communications stream between the White House and Russia.

Australia has fought with the U.S. in every major conflict since World War One.

McCain told attendees at a security conference, America is “Going through a rough period,” and urged Australia to “remind us always just how much is at stake.”

Heading to the Pacific Islands, McCain said he and the U.S. President agree on some things, including support for military funding.

McCain said he plans to introduce a bill that would significantly increase funding for America’s military when he returns from his trip.

He also said he is supporting an initiative to bolster military presence in the Asia-Pacific region.

On Monday, North Korea launched its latest missile approximately 250 miles into the Sea of Japan, where it landed inside Japan’s exclusive economic zone.
