President Donald Trump has drawn a parallel on Thursday between US strikes on Iran and Japan's 1941 attack on Pearl Harbour, as he defended the war he launched against Tehran while meeting Japanese Prime Minister Sanae Takaichi in Washington.
"We wanted surprise. Who knows better about surprise than Japan? Why didn't you tell me about Pearl Harbour?" Trump replied when a journalist asked why he had not told allies about his war plans.
"You believe in surprise, I think much more so than us."
Takaichi's eyes widened, and she shifted in her chair as Trump, seated beside her in the Oval Office, evoked the moment that drew the US into World War Two.
The Japanese attack on the US naval base in Pearl Harbour, Hawaii, on December 7, 1941, killed 2,390 Americans. The US declared war on Japan the next day, with President Franklin D. Roosevelt calling it "a date which will live in infamy."
The US defeated Japan in August 1945, days after the US atomic bomb attacks on Hiroshima and Nagasaki killed hundreds of thousands of civilians.
Trump's remarks received a mixed reaction on the streets of Tokyo on Friday.
Yuta Nakamura, a 33-year-old engineer with a petrochemical company, told Reuters that Takaichi had been put in "a very difficult situation," praising her for doing well by "avoiding upsetting Trump."
"Personally, I took President Trump's remark as just a joke. But because of her position, if she laughed too much, she'd likely face criticism, so I imagine it was quite hard for her to react."
Tokio Washino, a retiree, said: "Given the historical context of Japan having done that, and with Donald bringing it up as an example, it makes me feel a bit uneasy as a Japanese citizen."
