The White House is set to release President Donald Trump's 2027 budget Friday, a sweeping blueprint that could boost Pentagon spending to $1.5 trillion, the largest of its kind in decades, as the U.S. focuses on military investments rather than other domestic programs. Even before the U.S.-led war against Iran, the Republican president had indicated he wanted to bolster defense spending to modernize the military for 21st-century threats. Separately, the Pentagon last month proposed $200 billion for the war effort and to backfill munitions and supplies.
