This is ironic - from that article, though:
Amid the growing dispute between the two countries, the British embassy in Tehran was forced to be closed Wednesday after being hit by a number of shots fired from a nearby street.
I can not expect any changes in Iran while there are big interests and benefits for the Big Powers in Iran.
As long as UK/EU/ and some elements in the USA have benefits in this current Iranian govt, nothing will happen.
