Trump administration's 'maximum pressure' strategy against Iran not working: Analyst

A political analyst said an attack on US embassy in Baghdad by Iran-backed militiamen showed Trump administration's "maximum pressure" strategy against Tehran was t working.

Will Ruger, vice president for research and policy at Charles Koch Institute, said strategy of heavy sanctions was t creating a "docile" Iran but instead "creating more hostilities and more challenges".

militiamen withdrew from embassy compound in Iraqi capital on Wednesday after two days of clashes with American security forces.

attack and its volatile aftermath prompted Pentagon to send hundreds of additional troops to Middle East and US Secretary of State Mike Pompeo to delay a European and Central Asian trip.

Ruger said Pompeo's decision to delay overseas visit could be his way of "signaling" gravity of situation to US President Donald Trump.
