If timing is everything then it looks as if someone put it all into 04.00, Sunday 11 April. That’s when an explosion in Iran’s Natanz nuclear facility blew up the electricity supply to what is the Islamic Republic’s uranium enrichment centrepiece.

Fereydoun Abbasi, the head of Iran’s energy committee, said, “The enemy’s plot was very beautiful…. They thought about this and used their experts and planned the explosion so both the central power and the emergency power cable would be damaged.” The blast, condemned as “nuclear terrorism” by Tehran, occurred a few hours after Iran announced it had successfully installed advanced enrichment centrifuges.
