In his farewell speech, outgoing NATO Secretary General Jens Stoltenberg cautioned the United States and Europe against the dangers of isolationism, especially amid the potential return of Donald Trump to the White House. He emphasized that prioritizing short-term national interests over long-term collaboration would undermine security, stating, 'Isolationism will not keep anyone safe.' Stoltenberg highlighted the need for NATO allies to increase defense spending, noting that while 23 of the 32 member nations are projected to meet the target of 2% GDP on defense, it is insufficient in the wake of ongoing threats, particularly from Russia. He reiterated the importance of strong military support for Ukraine and warned that any future peace negotiations must be backed by robust defense commitments. As Stoltenberg prepares to hand over leadership to Mark Rutte, he reflects on a decade of increased military expenditures among European allies largely driven by the conflict in Ukraine. The NATO chief's remarks underline the alliance's current unity and its critical role in ensuring collective security against adversarial powers.
