Why are relations between Algeria and France so bad?

The kidnapping of Algerian government critic Amir Boukhors in France has reignited tensions between Algeria and France, with both countries expelling each other's consular staff. Boukhors, an online influencer who faced extradition attempts by Algeria for decades, was reportedly kidnapped amid claims of a plot to extradite him. This latest incident follows a history of strained relations marked by France's colonial legacy, which still affects its interactions with Algeria over territorial disputes in Western Sahara. The diplomatic fallout highlights the deep-rooted animosities between the two nations, even as efforts are made to restart relations following decades of tension.
