The health of any political system, and surely Islam is a political system, can be determined by how they treat the women. This war is all about women, control .............domination.
Amer Mushtaq Butt doused the woman with petrol and set her alight as she was leaving her home in a Paris suburb.
Chahrazad Belayni, a 21-year-old Moroccan-born woman, suffered third-degree burns to 60% of her body.
Ms Belayni broke down in tears after the sentence was announced in court late on Thursday.
"It sets a good example. For women who are victims of violence, I think 20 years is a good step," she said.
Prosecutor Camille Palluel said Butt had meticulously planned his attack "to end the life" of his former girlfriend in an attempt "to restore his honour".
Butt set fire to Ms Belayni in the street in the impoverished Paris suburb of Neuilly-sur-Marne in 2005 after she ended their relationship.
