President Barack Obama pledged America’s “ironclad commitment” to anxious Persian Gulf nations to help protect their security.
He pointedly mentioned the potential use of military force and offered assurances that a potential nuclear agreement with Iran would not leave them more vulnerable.
At the close of a rare summit at the presidential retreat at Camp David, Mr Obama said the US would join the Gulf Co-operation Council nations “to deter and confront an external threat to any GCC state’s territorial integrity”.
The US pledged to bolster its security co-operation with the Gulf on counter-terrorism, maritime security, cybersecurity and ballistic missile defence.
