If you wish to continue to troll I think we should end this here. Citizens of the DPRK are allowed to travel (just not defect to a country they are at war with) what stops them is visa refusals due to UN sanctions. The US and USSR were never at war that's why it was the cold war. India and Pakistan have normalcy as core parts of their ceasefire terms from the most recent scuffle (which never did escalate to all our war). Funny you bring up Iran who the US never declared war on but do you know where they aren't allowed travel by the American government, the DPRK because they are at war with them. Please educate yourself and grow up trolling is unbecoming once you mature past 12.
