Trouble is, nobody bothers doing anything if the migrants are only passing through.
Hungary for example did a Don, and closed borders with fences when this first kicked off.
Once they find a way round and into western Europe, they're on the home straight.
No proper coordination amongst the countries as they have differing views.
I don't see this as an issue with the EU per se, as its more widespread. However, its Remarkable how many of them seemed determined to get here. Even the French said some time ago that we were too soft, and its driving the demand.
Also remarkable how smugglers are able to buy, deliver and launch so many dinghies etc with relative impunity.
