There's a reason they started burning down hotels in Ireland. The good news is that high rate is a relatively recent development and they reacted much quicker than say Canada, so even though it's bad right now not nearly as much damage has been done

Can is be that France and UK do not account for colonies?

Present colonies? Sure. But France doesn't have that many colonies left. Former colonies? Unthinkable.

I think this explains it: France had a mess on its hands before 2000. And immigrants have a way higher birthrate, so the issues grow exponentially.

That said, this graphic does not account for two things:

1. the more unlivable a place becomes, the more people leave - and thus the lower net migration will appear. If a million natives leave and are replaced with 1 million Muslims, this will appear as 0.00.
2. The lowest being 5% of your population being the result of extra immigration is still astonishingly high. For France, it is 3.5 million. That said, I think a significant part of that will be from within the EU and thankfully for France, it's not a highly sought destination for immigrants like Germany and the UK are.

France has over had over a thousand terror attacks since 2000. Even if their numbers of imports are lower, the quality of the imports are worse. You'll notice that Australia doesn't have a child-rape gang crisis like England. France imports terrorists, the British import pedophiles, and Australia imports Chinese shop-keeps. Hence, though their numbers are worse, the severity of the problem is not as extreme.

Thomas Sowell tried to explain this in autistic detail in "Immigration And Cultures", because when and where you import immigrants from is more important than raw numbers. Raw numbers just magnifies the problem (or benefit).

There's quite a large number of "transitional migrants" (or whatever the official term is) where they entered through other nations but are squatting in France waiting to get to UK or even softer countries.
The gov't lacks the stones to actually move them out, ofc.
