. Nurses' associations and war in Ukraine. 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.
