The Constitution’s Forgotten Term Limit on Military Power

That guarantee, enshrined in the Constitution’s text, is now largely theoretical due to an obscure 1904 Solicitor General opinion that has proven to be a footnote to history — until now. The Framers’ fears are being realized: troops are being deployed in American cities, Congress has not cast a vote on the Iran War authorization, and President Trump signed into law a four-year military and ICE funding package buried in the One Big Beautiful Bill Act (OBBA) that insulates militarized immigration enforcement from congressional control.
