@Ancientofdays: The countries you have listed with no JWs is not accurate.
I can assure you majority of them have missionaries assigned to them. These countries fall under undisclosed location or other countries. In these countries JWs are under ban and restricted activity. Locals get into prison for preaching and any proselytising activity. Missionaries, usually assigned from a country that is an allied country with the government get deported.
I personally know 4 missionary couples who were assigned in Egypt and several brothers there.
All Gulf countries have at least 1 congregation in them - no ministry just meeting, although they are allowed to engage in informal witnessing to friends.
To be honest with you, i lived in a country under ban which is not on your list, and it was really nice. No ministry, 1 evening for meetings in a week, and never heard one JW say we are under persecution. Also other Churches had similar situation.
NB: at twickenham international convention i heard they had deligates from gulf countries. Cant confirm since i did not meet any.
