The 110 year old alliance between France and Britain is over. In the late 1800s, this alliance was forged between two nations who had been traditional enemies, out of common interests. The alliance was deepened through 2 world wars and, for all the occasional friction, a cold war.
However, it could easily have gone differently. But for a few decisions made on both sides, the alliance could have been Britain/Germany, with France/Italy/Spain on the other side.
That it has now broken up is simply a return to the world as it existed prior to 1890, albeit with a new power leading the Anglosphere.
I hope you're right about a close alliance between Britian and France being permanently damaged. However I think there are way too many people in Britian with that pesky Globalist "One Worlder" point of view that wouldn't want to be cut off from anyone, ever, because we're all citizens of the world.
More importantly from the EU via France since they got themselves into that Marxist quicksand and now they can't get out.
I hope Britian becomes anti French, a division in the EU would weaken France so they couldn't keep there welfare state alive on the backs of smaller EU countries.
