The calm does have a storm contained. They may be a restrained people in that they do check their emotions in public, but that is not the whole picture. Middle eastern peoples are more passionate and verbal in their emotions, unrestrained you could say. Japanese reserve these emotions but they do have them, social norms just contain them to the private realm. A big cultural difference. That and the understatement of the British ( honour codes of behaviour in Japan) make Japan seem a calm people in a crisis but the storm still rages.......you just do not see it's face. Israelis are a different people and express differently. The two can not be compared but in context of their own cultures.
