Donald Trump will face major geopolitical challenges when he takes office. 

In this Conversation, Eric Edelman, former ambassador to Turkey and Finland and Under Secretary of Defense, shares his perspective. As he explains, Trump will face major decisions on all areas of the geopolitical landscape early in his term. Edelman argues that Israel’s military successes have weakened Iran’s “axis of resistance” and opened up new opportunities—but also raise the threat of Iranian nuclear breakout. Meanwhile, the war in Ukraine rages, the situation in Europe remains uncertain, and China’s military buildup increases. To meet the threats around the globe, we need to build up the military and defense industrial base, embrace American leadership, and strengthen our alliances. Will the Trump Administration do so?
