Trump's criticism of Japan came up during an interview with Fox Business Network when he was asked about the possibility of bilateral trade deals during his G20 trip, where he will meet with several colleagues, including Japanese President Shinzo Abe.
"Let me start with a general statement – almost all the countries of the world are using tremendous benefits," Trump told Fox Business over the phone, repeating a common refrain from his 2016 campaign.
Then the president criticized NATO in general, before awarding Japan the terms of its military alliance with the US.
"If Japan is attacked, we will fight World War III. .. with our lives and with our honey, "he said, adding," If we are attacked, Japan does not have to help us at all, "said Trump. Japan, he claimed, "can see it on Sony TV, okay, the attack."
And apparently, Trump once again referred to the same agreement in his interview with Fox Business on Wednesday.
The US has been a close military and diplomatic ally of Tokyo for more than 70 years. The two countries first signed the Treaty of San Francisco in 1951, officially ending World War II.
However, Trump has repeated military allies in East Asia asked to pay for their own defense to prevent the end of the US military presence in the region and to encourage Japan to buy more American weapons to better protect itself from threats from North Korea.
Before the G20 summit in Japan, Trump once again expresses frustration over military agreements with important allies.
Trump has long criticized the fact that NATO countries are not spending enough on defense and reach the Alliance's proposed 2% of GDP target.
While Former Presidents Had Received Similar Criticism Trump has made NATO members' defense spending a central theme of his presidential campaign and his government's foreign policy. He once described the Alliance as "obsolete" and has repeatedly criticized allies regarding the issue of expenditure and associated it with trade disputes with the European Union.
