Advisor to President: Iran is much patient, Saudis will come for talks

'It will take time for you to come to your knees and running out of oil revenues,' Aboutalebi said in his Twitter account. 

He said that the heavy cost of supporting terrorism, extremism and massacre will finally make Saudi rulers yield under financial pressure, according to IRNA. 

''Relations between your fathers and Iran used to be friendly for three decades. When the children become ministers, first of all, they criticize their fathers. This is megalomania.' 

'We are much patient until the heavy cost of the Saudi regional interventions gets you to a critical situation,' Aboutalebi said. 'You will come for talks.'
