The announcement that Cooper, commander of the US Central Command (CENTCOM), will participate in the negotiations is seen as a new diplomatic tactic, writes AP.
Trump's decision is also seen as a warning about the potential deployment of military resources. Cooper was involved in indirect talks between the US and Iran and participated in them in uniform.
Army Secretary Driscoll, a former career soldier, has been continuously participating in the Ukraine negotiations. So far, Trump has largely relied on Steve Witkoff, a real estate magnate, and his son-in-law, Jared Kushner.
