WASHINGTON: The US Congress is moving to tighten oversight of Pentagon leadership decisions and limit unilateral military action against Iran, in a rare bipartisan effort that underscores renewed tensions over presidential war powers and civilian control of the military. On Thursday, the House Armed Services Committee adopted a bipartisan provision that would require the Pentagon to notify Congress within five days whenever a senior military officer is dismissed, along with a written explanation for the decision. Lawmakers say the measure is intended to improve transparency over personnel changes at the top levels of the armed forces, where congressional visibility has traditionally been limited.
