No, Macron did not say that the Minsk agreements have no legal force or are worthless. 

In fact, during a phone call with Putin on February 20, 2022, Macron explicitly stated, "I never said that the Minsk agreements should be revised. I didn't say that in Berlin, Kiev, or Paris. I said that they should be accepted, and their provisions should be respected."

Macron consistently emphasized the importance of the Minsk agreements as a framework for dialogue and de-escalation before Russia's invasion of Ukraine.
