How Allah Judge North Korean ?

hey,hello there,first thing first,Im not a muslim but i have slight interest in this religion.There is a hadith that states that Allah have sent mesengers to all lands in this world and have told them about Allah..BUT,right now in the present time where there are no new mesenger since Muhammad was the last of them,my question is how will Allah judge the people of North korean,they are brainwash and deluded and have no idea what is going on in the outside world or whatsoever,they have no idea of Islam let alone other religions..will all of them go to heaven.I heard about this hadith where in judgement day there are group of people that says that they have not been informed nor have any messenger have ever come to them and Allah will give them a chance to follow hes command to enter hell...if they obey they will enter heaven instead,I do not know if this hadith is authentic or fake,but could this group be North korean? any thoughts??

Sir! Islam is well-famous since the days of its emergence. The people of North Korea have every idea what Islam is all about but they are not Muslims.
