In this case “Third World” was used as simply a shorthand term. Egypt, for example has a large fanatical religious group running around. Imagine if they obtain control, or bomb a museum ? Best keep the precious artifacts in Europe, for even in a war they were protected.
Quite right. There’s already a drive on to cover up representational art in Egypt, among other things, and tourists (as well as Egyptian Christians) have been murdered by terrorists (iow Moslems).
