Would someone explain to me why Ramzan Kadyrov and Shamil Basayev...?

Why are Ramzan Kadyrov and Shamil Basayev (deceased 2006) so fascinated by Che Guevara? Kadyrov has a picture of Guevara hanging on his wall and Shamil Basayev was obsessed with him (according to a former employer in Moscow)? Any theories? Please share. Thank you. This is for a research paper.
