I read that book and what Juan Branco say is that XN wanted to construct soft power relations with Emmanuel Macron to keep its influence. XN puts himself in a bad political position with Sarkozy.

In this book JB explain how rich peoples invest the political side in various ways to keep their benefits high. XN is one of them, specially because he was self-made and have no relations.

JB say the problem is not that rich peoples try to keep their influence, it's that noting prevent (and punish) them to do so.

It's not about being evil or not, it's about how evil can be part of the game (because political campaign funding).
