France directly aided the Hutu government because they were worried about Anglophone influence in the region. Both before, during and after the genocide, France helped the perpetrators. Even their "humanitarian" efforts were largely skewed towards helping Hutus. When the French and Belgians were busy evacuating their own expatriates, they refused to help any Tutsis, even spouses. They did help evacuate Hutus.
France supplied arms to the Interahamwe for Gods sake. The people that slaughtered women and babies, who skewered heads on spikes, threw grenades into churches full of innocent people and literally gang raped women to death.
I am strongly against historical revisionism and this recent obsession with holding current generations accountable for actions that occurred hundreds of years ago, but this is not either of those things.
The genocide was unimaginably horrific and France's complicity is well documented. It also happened less than three decades ago. This has nothing to do with patriotism, and France should feel immense shame for how it acted in Rwanda.
