How could the new US Congress bring about an end to the war with Iran? - explainer
Trump is expected to veto any measure to stop the fighting. It takes two-thirds majorities in both chambers to override a veto, meaning Democrats would need Republican support to overcome Trump
Assessment
The new US Congress holds the power to shape the trajectory of the war with Iran, but any attempt to force an end to hostilities faces a steep climb. President Trump's expected veto means Democrats must peel off enough Republican votes to reach a two-thirds supermajority in both chambers. The question is whether GOP lawmakers will break with the White House on a national security issue this divisive. The coming weeks will reveal if there is enough bipartisan will to override the president's war policy.
