As NATO marks 75 years, a revitalized Alliance faces an array of new challenges

As NATO marks its 75th anniversary on Thursday, the Alliance is seeing renewed dynamism, particularly with the recent accessions of Finland and Sweden. But the organization also faces multiple challenges, from the war in Ukraine to the possible return to power of Donald Trump in the United States. According to military historian Guillaume Lasconjarias, the transatlantic alliance finds itself in a state of “paradox” between a renewed sense of purpose and a wealth of new challenges.
