I would like to make a quick comment about this way of avoiding risk. When sanctions were applied against Iran, Iranian students here in Canada saw their bank accounts being closed because the banks did not know how to apply the sanctions.
Mr. Biersteker, sanctions can come in three categories, or have three purposes: to change behaviour, to impose a constraint, or to send a signal.
How would you describe the sanctions against Iran? Where do they fit in those three categories in terms of their effectiveness?
