I'm writing from Poland.

Iran and North Korea are for me two totally different issues.
There is no chance and wish to support the communist regime in Korea, although I can't see in Polish law any legal restrictions to communicate on internet forums and "exchange the experiences". But nobody does it and nobody wants to do it, when we know, that there's no free access to internet in N. Korea and any contact from there is surely "non private"

Iran is a different matter.
I know two or three Iranians from my activity with Linde (yes - Linde was and probably is doing the bussiness with Iran).

Generally Iranians I know are very nice and friendly people and they are really **** off because of their regime. They do the bussiness like us, they employ the people and are pretty reliable partners. And they want to be treated as normal guys, not regime agents.

I rememeber in eightees, when we had the martial law in Poland, there were some serious economical restrictions from western countries against the communist governemt, and paralelly the huge private or organizational aid from western citizens for Polish people. We remember that.

I think the actual Iran situation is somehow similar.

We here have no law forbidding to communicate private people with private people in Iran, specially when our area of activity is technical but definitely civilian.
