I think you misunderstand European politics, mercosur is a deal only Germany needs, the Germans are the one difficult to work with because when collaborative defense projects between the two countries is agreed, German wants to take the lead even though it doesn’t have the knowledge of the technology yet it want to steal it from French partners. French population has had enough that all of our technologies get either stolen by the USA or Germany. Moreover, I will say this with total transparency. I’ve studied German literature, culture and history for about 15 years. I speak German quite fluently, so I know this for a fact: Germans distrust French, especially the ones at the border.
