I am not impressed by your paranoia, Bearded Bruce, and I think you are a victim of propaganda. Iran has not attacked its neighbours. Iran has not invaded any other country. Iran is in a defensive posture, and for very good reason, because two of its immediate neighbours have been attacked and invaded by the USA and Britain.

In about the last 20 years the following full-scale military invasions have been launched in that region:

Iraq invaded Iran (with encouragement and aid from the USA)
Iraq invaded Kuwait
The USA and Britain invaded Iraq (twice now)
Israel invaded Lebanon (twice now)
The USA and Britain invaded Afghanistan (over a criminal act committed not by Afghanistan, but by a secret terrorist organization based in a number of different places, including Afghanistan)

Iran has not invaded anybody during that same period. Iran has been attacked and threatened with further attack.

They are the ones who ought to be paranoid, Bearded Bruce, and they have every reason to be testing and perfecting whatever missiles they have, and they also have a legal right to pursue a nuclear energy program if they want to. Their nuclear reactor is not an illegal device, and their enriching of uranium is not an illegal act, it is a perfectly normal thing for them to do if they are pursuing a nuclear energy program.
