I feel strongly about that because from 1985 on there's been a fairly mass migration movement, perhaps the biggest in history, that's taken place from countries in the developing world into the industrialized world of western Europe and North America. For the most part, that's been an irregular movement and, in particular in the case of Europe, an unwanted one.
It took place first in the 1960s. It began in the 1960s with guest workers coming into European countries on a temporary basis, but none of them ever went home, and that has continued with asylum seekers.
I think last year some 500,000 asylum seekers came into western Europe and North America. These are people on the move, and you can't blame them. But if the movement is irregular, and these people are not welcomed, and they're not in any way managed, and they're not helped in any way, they undermine the confidence of the source countries.
