In an interview with Fox News TV, former US ambassador to the UN, John Bolton, said: I think nothing can compel Iran to cease its nuclear programs. This regime has had this program for 20 years and the latest thing they’ve announced indicates this regime’s persistence in the same track. That is why I think the path of advancement of the Iranian regime in completion of fuel cycle on the one hand and the path of diplomatic sanctions on the other hand has reached to its end.

Bolton said: Our options are very limited; either a regime change (in Iran) or use of military force vis-à-vis its nuclear program as the last option
