the first video doesn't show anything implying him being connected to isis. he's bearded and not a slav? we have tatars, as well as ichkerians (and others) fighting on our side, yes. if you're so blind to race nuance that everyone "like that" is isis to you i must question whether you're actually jordanian. that guy speaks literally perfect modern "russian" (moscowian) language, by the way. how many isis can boast of that? the second video has a guy speak perfect moscowian as well, and his first specific blame in what i expect is a much longer speech is about ichkeria. so i'm hazarding a guess that he is from ichkeria. the flag is either youthful edge or he was seduced by someone promising easy solutions and simple answers to everything. many such cases, since the dawn of humanity.
