it seems that the west wants sanctions at any price, even if iran complies. I reckon that what was important to the u.s and europe was that iran should comply to them not their demands. the demands brokered by turkey and brazil are essentially met, allowing their enriched uranium to be transfered for fuel rods from france but keeping them in turkey instead of russia. The u.s will require that iran halts all enrichment after the trade, that is clearly unnaceptable as it forces iran to be the only country not allowed to enrich to civilian levels and will have to procure its reactor fuel from the west. U.S is clearly pouting that it was left out of the loop on this one, as will france, uk and germany. As for Israel, a military strike on iranian installations was always number one priority, that does not change today.
