Sony's had a truly dreadful couple of years, what with lost market share, getting hacked by North Korea and suffering the rising yen's wrath. To the list of indignities, the Japan Inc. icon can now add getting roped into Donald Trump's anti-Japan tantrums.

"You know we have a treaty with Japan, where if Japan is attacked, we have to use the full force and might of the United States," the Republican nominee for president said Friday. "If we're attacked, Japan doesn't have to do anything. They can sit home and watch Sony television, OK?

The real question is whether Trump's geopolitical ignorance knows no boundaries, even on America's key allies? A quick Google search would inform Trump that the U.S. penned the post-war Constitution barring Japan from sending troops overseas. It would tell him that Japan put boots on the ground in Iraq anyway to aid the U.S. in the early 2000s. It would school Trump on Prime Minister Shinzo Abe's push to change Article 9 of the Constitution so Tokyo can join America's future military adventures.
