The US Defense Department's latest National Defense Strategy (NDS), released under the Trump administration, has been criticized for its glaring omission of climate change as a national security concern.This exclusion raises questions about the administration's understanding of the multifaceted threats facing the United States today.The NDS is characterized by a reliance on familiar Trumpian rhetoric, including phrases like "America First" and "making America great again." However, critics argue that the document reflects a troubling narrowness in defining security challenges, particularly by neglecting climate change, which has been recognized as a critical factor affecting global stability and US military operations.

foreignpolicy.comThe Trump administration's approach to national defense is further complicated by its broader geopolitical strategy, which focuses on burden-shifting and prioritizing economic interests over collaborative security efforts.This posture may alienate traditional allies and partners, who may feel compelled to realign their interests in light of the US refusal to acknowledge shared threats, including climate impacts.Such dynamics could inadvertently push allies closer to adversarial powers that are more attuned to the implications of climate change on security.

foreignpolicy.comIn summary, Trump's National Defense Strategy represents a significant step backward in recognizing and addressing the multifaceted threats posed by climate change.As the US military grapples with increasingly complex challenges, a more comprehensive and realistic approach is needed—one that includes climate change as a central element of national security planning and strategy.
