As the U.S.-Israeli bombing campaign against Iran escalates, Republican lawmakers on Capitol Hill are going to great lengths to avoid using the word 'war' to describe the conflict. They are instead referring to it as a 'major combat operation,' a 'mission,' or 'hostilities,' reflecting the tricky politics of an unpopular war and the legal and constitutional questions raised by President Trump's decision to launch the offensive without congressional approval.

Why it matters

The verbal gymnastics by Republicans highlight the political and legal challenges of the Iran conflict. Officially declaring it a 'war' would require Congress to authorize military action, something most GOP lawmakers are reluctant to do. It also underscores the unpopularity of the conflict, especially among Trump's base who elected him as an 'America First,' anti-war candidate.

The details

Republican lawmakers have employed a narrow definition of what constitutes a 'war' in order to avoid acknowledging that the U.S. is engaged in one. They argue that since Congress has not formally declared war, the current military operation does not meet that threshold. However, the administration's own rhetoric, including Defense Secretary Pete Hegesth's promise of 'death and destruction from the sky,' suggests the conflict has escalated well beyond a limited 'mission' or 'hostilities.'

  • The U.S.-Israeli bombing campaign against Iran began four days ago.
  • The Senate is preparing to vote on whether President Trump needs congressional approval for the military mission.

The takeaway

The Republican lawmakers' reluctance to call the conflict with Iran a 'war' highlights the political and legal challenges the administration faces, as well as the unpopularity of the military action among Trump's base. The semantic gymnastics suggest an effort to avoid the constitutional requirement for Congress to authorize a formal declaration of war.
