All this is about is saying that human rights, like other rights, are not absolute, but only for as long as they can be afforded. Just like saying pensions should have the triple lock (because UK pensions are low in comparison to other European countries) but not when the economy has been mismanaged.
And of course, in typical politician headline instant gratification, doesn't deal with why there is an increase in the number of asylum seekers ie asset stripping of natural resourses, climate change, propping up regimes by the very countries now whining about having to deal with the consequences of that.
