Until recently, the military has dominated the national defence policy-making and military strategy process in Taiwan. Public debate did not occur because defence issues were classified or viewed as too politically sensitive. Therefore, non-government civilian institutions had little political or financial incentive to become involved. However, as Taiwan has moved towards a more open society, the Legislative Yuan, media, universities and non-profit research organizations have become more active in questioning the tenets of Taiwan's defence policy. Their impact has been limited, though, because of the lack of civilian expertise in defence matters. Furthermore, Western authors have not written extensively on Taiwan's internal defence policies because most information published in Taiwan is written in Chinese only.
