随着特朗普政府的外交紧张局势和政治言论升温，加拿大军方军官越来越不愿接受在美加联合指挥机构的任职，尤其是北美航空航天防御司令部（NORAD）。现任和前任官员透露，由于担忧晋升前景、作战权限受限，以及家属对反加情绪的担忧，加拿大难以填补美国指挥体系中的高级职位。
U.S.-Canada Defense Ties Fray as Canadian Officers Hesitate to Accept Joint Military Postings Rising diplomatic tensions and political rhetoric from the Trump administration have led Canadian military officers to increasingly avoid postings at integrated U.S. commands, notably the North American Aerospace Defense Command (NORAD). Current and former officials report that Canada is struggling to fill senior U.S. roles due to promotion concerns, limited operational access, and family apprehension over anti-Canadian sentiment.
这种紧张关系源于贸易争端、公开质疑加拿大主权的言论，以及美国防务官员的贬损性言论。尽管北美航防司令部坚称双边职位依然人员齐全且运作正常，但摩擦已导致加拿大暂停部分防务采购项目，包括美制“黑鹰”直升机，并重新审视其他合同，双边关系持续恶化。
The strains follow contentious trade disputes, public rhetoric questioning Canadian sovereignty, and derogatory comments by U.S. defense officials. While NORAD maintains that bilateral positions remain fully staffed and operational, the friction has led Canada to pause certain defense acquisitions, including U.S.-made Black Hawk helicopters, and review other contracts amid deteriorating bilateral ties.
