As Harvard professor Graham Allison says:
I worry about those "hothead nationalists" too. A Chinese friend says that his relatives bought their first car last year but have kept it garaged ever since because they fear the vandalism some of their neighbors have suffered --because it's a Japanese model car. “The mechanism in 1914 is instructive. Who could imagine that Serbian terrorists could kill an archduke no one had heard of and trigger a great war, at the end of which all contestants were devastated? My view is that the Chinese leadership has no intention of challenging the US militarily, yet. But what about the hothead nationalists in China or Japan?”
Until the various parties are willing to try to negotiate a settlement, they should at least work to develop emergency communications links ["hotlines"] and rules of the road understandings like the U.S.-Soviet incidents at sea agreement of the 1970s. Such mechanisms were lacking in 1914.
