It would be nice, but I’m pretty certain it won’t make the slightest difference. I’ve seen so many posters talk about how awful it is that we’ve lost the ability to return people to Europe since Brexit and it’s just not true. Dublin was not the answer to lowering arrivals, like so many people think it was, and us withdrawing from it hasn’t caused the increase.
I hate to cite Wiki anything but the sources they use are on there and are reputable, so it’s convenient. ‘Of the 128,000 migrants, caught by German police near the borders in 2023, only 7.9% had been registered before by an another European County and the fingerprints of the rest could not be found in the Eurodac database.’ That means that Germany would only have been able to return 7.8% of asylum applicants, assuming they were able to meet the other conditions and in the timescale set out in the agreement. That barely touches the sides.
It’s nice to use it if you can, but it’s not doing huge amounts for Germany now, just as it didn’t do huge amounts for us when we had it. I don’t think the numbers support it being the huge loss that lots of people believe it to be.
