Trump's second inauguration
Donald Trump was sworn in for a second term, becoming the first U.S. president since Grover Cleveland to return to office after an electoral defeat. He immediately issued pardons for many January 6 defendants and signed executive orders on immigration, energy, and foreign policy.
Israel and Iran fight a twelve-day war
Israel struck Iranian nuclear and military sites, and Iran responded with missile attacks as the United States entered the conflict with strikes on Fordow and Natanz. A ceasefire ended the fighting after twelve days, but the confrontation left the region closer to direct state-to-state war than at any point in decades.

Israel and Hamas agreed to a phased ceasefire and hostage exchange after fifteen months of war. The pause allowed more aid into Gaza and brought hostages and prisoners home, but it left unresolved the wider political and military terms of the conflict.
