The current war on terror is not comparable to past wars during which Habeas Corpus was suspended. Both the Civil War and World War II were openly declared wars of limited duration following invasions by hostile forces. The “war on terror” is nebulous and open-ended. In any case, history has harshly judged arbitrary detentions during wartime. Lincoln’s Civil War detentions and Roosevelt’s Japanese internment camps of the 1940s are embarrassing chapters in US national history. The fact that former presidents improperly suspended Habeas Corpus is all the more reason to exercise caution now. Additionally, the suspension of Habeas Corpus by the UK in 1971 arguably strengthened the cause of the IRA, and made it easier for the organisation to recruit members. Western governments should be careful not to repeat the mistakes of the past
