Yes they can..France has nukes and is a member of the United Nations security council so is backed up..
But that's not how you fight France.
With France the connection to these 14 African nations and it's leeching off of them is a direct result of colonialism.
Colonialism isn't just economics it's cultural as well. You need to first off cut cultural ties that may exist with France.
That means French language is outlawed.
Burundi I think wanted to try that in order to get the French off their backs.
You remove all vestiges of France from your country so you have nothing in common. French tourists start paying 100 000 euros for a single visa etc.
They just need to gang up of France at the United nations and make their case against France and present evidence as to the complicity of France in the deaths of the Rwandan and Burundi presidents leading to the genocide in addition to Gaddafi killed by Sarkozy and Hillary.
If the UNITED backs France then you leave the UK liken the ICC.
There are huge obstacles every step of the way of this plan. However, anything is better than the alternative in my book. No one said it was easy.
