Anyplace where there are displaced persons, pretty much, John. During World War I, During World War Two, after World War Two until the Jews tried to get into Palestine, when I believe it was considered an invasion by the Brits and by the local Palestinians. And the recent human Rights crises all over the world. We tend to think of these as Human Rights Crises, John, though some countries have trouble dealing with the displaced populations and they often are not assimilated, or are assimilated poorly or are kept as guest laborors in the country or some such.
In fact, I'd venture to say that most people in this country, while they may not know what to do with the migrants, would find the word "invasion" a bit odd. The word suggests an army, which would have an organizing principle and a structure of organization, which the migrants certainly do not have, or it might also be an extremely poorly chosen metaphor for an insect swarm, which would suggest that they aren't even human, which one might hope is language that no citizen of this country would use about a fellow human being.
Am I misreading you, somehow, John?
