On a more general note than the answer you already got, he is extremely authoritarian, absolutely never listen to the people same for his government, refuses to change his mind on anything and isn’t open to discussion on anything. Even with the state of emergency being declared on part of the territory, he didn’t give anything away to make it stop.
So he destroys the social net, and people’s beliefs in democracy : that’s the two things you have to do to raise far right anywhere.
Tactics against the far right? What tactics? He has done absolutely nothing against the rise of the far right and helped it so many times.
Hell he has become more extremist every year himself.
What works against the far is known, we have already done it in the past : everything done by the CNR after the war. A social safety net. He has done nothing but destroying it, not only has he failed to fight the far right, he is actively enabling it.
