President Donald Trump will ask Congress to enact a massive increase in defense spending in a discretionary budget proposal Friday, while also renewing his push for steep cuts to domestic programs.

The budget requests $1.5 trillion in budgetary resources for defense, a significant increase over the $1 trillion sought for fiscal year 2026. The new figure includes $1.1 trillion in base discretionary budget authority for the Department of Defense and $350 billion in additional resources as the US carries out its war on Iran.

Discretionary nondefense spending would be cut 10%, by about $73 billion, according to fact sheets circulated by the White House in advance of the annual budget release Friday.

The president’s decision to seek a dramatic rise in the Pentagon’s budget — the largest single-year increase since World War II — comes as polls indicate he’s struggling to convince many Americans of the wisdom of the war in Iran.
