Countries that you should probably never visit

What war is there in North Korea? It's a completely safe place to visit, as you'd be confined in an organised tour group anyway. Iran is also very safe and a beautiful country to visit, just difficult if you hold an American, British or Canadian passport (and impossible for the Israeli of course). Iraq is also popular for Shiite Muslim pilgrims visiting Najaf. Somalia is not safe because of Al Shabaab, not pirates (unless you visit the country by sea). Somaliland on the other hand is quite stable. The country missing here is Afghanistan, as foreign troops withdraw and the Taliban is getting hold of the country once again. It's more likely to get killed in the United States from gun violence, hate crime (or building collapse to add to the list) than visiting North Korea or Iran.
