O'Neill was in permanent conflict with Portugal. While other contemporaries wrote poems that protested against national life under Salazar, O'Neill's attack ran deeper. Poems such as Standing at Fearful Attention and Portugal suggested that the dictatorial regime was a symptom (the worst symptom) of graver ills – lack of courage and smallness of vision – woven into the nation's psyche. Other poems, such as Lament of the Man Who Misses Being Blind, seemed to hold religion and mysticism responsible for an obscurantism that made change difficult if not impossible.
