Senate blocks war powers measure and House follows suit – now president can bomb Iran free from congressional interference

Before US troops invaded Iraq, George W Bush asked Congress to pass a resolution authorizing military force against Washington’s longtime nemesis, a request that lawmakers obliged.

Twenty four years later, the United States is at war with a different Middle Eastern rival – Iran – under a different Republican president – Donald Trump. But this time, the president did not bother to seek permission from the Senate and House of Representatives before joining Israel in launching the air and naval campaign. And far from objecting, Congress’s Republican majorities have simply stepped aside.

The stage is now set for Trump to continue his military campaign against Iran free from Congress’s interference, despite shifting explanations by the president and his administration of its objectives, and concerns from lawyers that the war is illegal and costing unnecessary money and lives.
