So far, the campaign, which was given a platform at the Munich security conference instead of the Iranian foreign ministry, has been unable to persuade either the EU or the UK to proscribe the IRGC.

The CIA director, William Burns, said on Sunday that Iran was nearing the uranium-enrichment level of a nuclear state, but had not resumed weaponisation.
