Because the Witnesses reckon on being no part of the world with their policy of not saluting the flag ,disregard for national anthems, playing no part in the defence of their natural nationality and definately no partaking in elections, should the top notches at headquarters issue them with Kingdom passports.? They are commanded to keep seperate from the world and they need to travel to the far corners in order to spread the word but is a dual passport really out of the question,? think how proud they would be going through passport control into the New world while everyone who isn't a proud holder is fast tracked to oblivion.
With all the printing facilities at HQ surely it would would be an easy peasy arrangement to set up and it would be a tremendous morale booster during these long difficult days since 1914 I mean 1975, silly me.
God's Kingdom reigns could be on the front cover but what else could they stick on it and any suggestions on passport colour?
