Saber-rattling by China over the Senkaku Islands, most recently in the form of locking weapons on a Japanese ship and helicopter, have led some analysts to warn of war between the two East Asian countries. These analysts go further to question whether the US treaty commitment to Japan’s territorial integrity would hold in this case (Wall Street Journal).

Such warnings are overblown. Militarized jostling of this sort is normal for low-intensity territorial disputes. All parties — including China — recognize that war would be counterproductive. China regularly activates media coverage with its mildly belligerent actions in order to bolster and maintain its long-term claim to the islands should the case go to an international court in future. Japan is a key US ally and trading partner. There is no question that were war to occur between China and Japan, the United States would defend its ally.
