I feel like you confuse 'Germany not leading' with 'Germany not letting France lead'. Which is aboslutely not the case.

The first article: France leading would be France sending tanks and then Germany following. How is Germany 'not letting' France do that? Germany has shown very well that they will let France lead. After France decided to send their AMX-10, Germany followed less than 24h later.

Same with Poland. If they want to 'lead' then maybe they shouldn't push Germany to send Leopard 2s first, hide behind that they would only send Leoaprd 2s in a coalition. Just send the export request already and Germany can approve it like Habeck has already said.
