Controlling escalation as a strategy has now become a key principle of crisis management. This paper is going to analyze the behavior pattern of Taiwan Strait crisis and assess the feasibility of a decisive battle outside the territory, proposed by President Chen Shui-bian, from theoretical perspective of crisis management. We argue, with the political uncertainty between Taiwan Strait, adopting the strategy of outside the territory, passing the message clearly at the same time, it should effectively prevent Chinese military provocation from happening. As a result, military competition will be even more intensive.
