Iranian officials have been shocked by the display of European unity, considering that Iran accounts for 20 percent of oil imports to Europe. The oil measure will only fully take effect on July 1, to give key buyers – especially Greece and Italy, which are facing debt crises – time to find alternative sources.
The unprecedented EU measures are the latest to be imposed upon Iran, in addition to four rounds of sanctions from the United Nations Security Council and a raft of American measures.
Iran says it will not slow or suspend any part of its nuclear program when under pressure. Few expect sanctions alone to prompt Iran to capitulate on its nuclear program, which Tehran says is for producing nuclear energy, not bombs.
"There is a genuine fear here that once the West senses weakness, it won't stop at the nuclear dossier," says the Iranian analyst. "The threat of regime change is also increasing.... I think the Iranians think: 'Well, if I was in their [Western] shoes, why stop here?'"
American and Israeli intelligence, along with inspectors of the UN's International Atomic Energy Agency, conclude that Iran has conducted weapons-related work in the past, but say they have no evidence that Iran has decided to make a nuclear device.
