The tragic irruption of war with all its scenarios of horror and destruction in the heart of Europe has documented the depth of the absence of a culture of peace in the international community of States, which have not be willing nor capable to propose a credible platform leading to a diplomatic solution of a conflict where all big powers are complice. While the strictly health related impacts represent a direct and specific interest and challenge for the nursing profession, it is clear that we are facing a future where a new awareness of being citizen of a world which requires a different culture and commitment must become part of our training and strategies of presence in the society. A survey of the positions assumed by the nursing organisation at international level, together with few model reflections on the broader implications of what we are living, is proposed as a first expression of a long term commitment and interest.
