Iremos argumentar que este é um conflito militar com aspectos únicos e um desafio sem precedentes à ordem global vigente. Sobretudo porque se trata da primeira guerra de conquista imperial por uma grande potência desde 1945, desafiando a norma global contra esse tipo de agressão vigente desde essa época. Esta guerra também oferece um teste real à evolução da doutrina e das tecnologias militares cujas implicações seria um erro ignorar. Não podemos ter certezas quanto ao desfecho desta agressão armada russa, mas já é possível tirar aqui conclusões preliminares sobre as suas implicações em termos do futuro da guerra. Terminaremos este artigo apontando algumas dessas implicações em termos de segurança e defesa globais, e também para Portugal.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract We know that the Russian invasion of Ukraine is the most intense war in Europe since the end of the Second World War. We will argue that this is a military conflict with unique aspects and an unprecedented challenge to the global order. Above all, it is the first war of imperial conquest by a major power since 1945, challenging the global norm against this type of aggression that has been in force since then. This war also offers a real test of the evolution of military doctrine and technology, the implications of which it would be a mistake to ignore. We can&#8217;t be certain of the outcome of Russian aggression, but we can draw some preliminary conclusions about its implications for the future of the war. We will conclude this article by pointing out some of these implications in terms of global security and defense, namely for Portugal.]]></p></abstract>
