It needs to be part of a co-ordinated set of actions to eliminate the overall set of pull factors so as to make the UK no more attractive a place to come to than any other country.
That's not really a satisfactory answer. Given you specifically wanted the approach to lifesaving to mimic "other (unnamed) Western countries", I'm curious as to what, exactly, the approach is there and what we should be emulating.
Now I don't actually know what, say, the Italian coast guard does with relation to:
It appears to be that just the fact of them being an overloaded craft may be triggering rescues, in a way that it is questioned whether other countries would take the same approach.
Do they take the same approach or not? Do you know? Because I genuinely don't, but my vague understanding is that Frontex actively surveil the southern Med to look for crossings and the Italian coast guard picks them up before there is any mortal danger.
There are basically two options - one, you send out the RNLI to rescue people who are at risk in your waters in totally unsuitable craft. This means people don't die, and it also means they get dropped off somewhere dedicated where they can be processed.
The other option is to just not do that. This will result in more deaths in our waters which are our moral responsibility. For those who succeed, they will not land in Dover but may well use many crossing points and landing areas. So you'll get random groups of men and families landing in Dungeness or Hythe or Hastings or perhaps even somewhere in the countryside where they can just walk inland and fade in.
The dog whistle is always "well if some more people died in the Channel maybe it would focus some minds", so if you don't want people to think that about you then it probably would help not to suggest the RNLI are making the situation worse. Because if they weren't rescuing people, the second scenario will happen. And if it was me and 40 of my mates risking our lives standing on a small dinghy built for 10 floating nine miles off the coast of Britain and someone spotted us, I think we would all agree the RNLI ought to come out.
The UK is a de factor attractive place to claim asylum because we speak English. The vast majority of asylum seekers in the UK speak English well or very well. And I'll say again - this situation is the creation of the people who hate it the most; Reform voters and Brexiteers. They're the ones who took us out of the EU, and hence out of Dublin III. But it's left to someone else to sort out, as usual.
My main objection to Reform voters is that, while I have sympathy with the basic principle that the social contract is just plain broken, they aren't actually looking for a solution, or to do any hard thinking or compromise or work collegiately. They just want to complain and be victims, and to be considered oppressed ("help I'm being invaded!"). It's a weird kind of reverse wokery which relies on identity politics, which is already very 2020 and sort of passé now.
