軍事互信機制在歐洲經驗的成功，不僅強化了歐洲各國互信，增加穩定及安全，也被廣泛的運用到其他地區。兩岸之間的軍事互信機制則在馬英九贏得總統大選後，又重新獲得海峽兩岸的重視，雙方都重申將在「九二共識」的基礎上，恢復包括「兩岸和帄協議」的協商。顯然雙方對重啟協商充滿期待，然而事實果真如此？建立兩岸「軍事互信機制」的「互信」或者說是「信弖」真存在嗎？現今兩岸尚未建立信弖之際，為不確定的發展和未來的緊張關係先行準備，透過各種方式來強化己方信弖與衛國意志是有其必要的。本文希從全民國防的概念意涵、理論與範疇，來釐清其核弖要素為何？其與近來討論甚為熱烈的「軍事互信機制」之間，又有何相互扞挌與矛盾之處？盼透過逐有脈絡的分析檢視，獲得啟示，形成共識，以維護國家安全、長治久安與永續發展。

The successful experience of confidence-building measures in Europe not only has strengthened the mutual confidence in this area but applies to other areas as well. Cross-strait confidence-building measures regained attention after Ma Ying-jeou won the presidential election. Both sides of the Taiwan Strait assert that they will return to the table of negotiation on the basis of Consensus of 1992. Obviously, both sides of the Taiwan Strait are looking forward to restarting negotiation. The fact is, however, that “mutual trust” or “confidence”, the essential foundation of building up these measures, does not exist. In this context, it is necessary for Taiwan to strengthen its forces, especially all-out defense for future conflict with China while the mutual trust between the both sides of the Taiwan Strait has not been established. This article will focus on the meaning, scope and elements of all-out defense, compare the key elements of all-out defense with those of confidence-building measures, and then analyze their contradictory situation.
