Unfortunately if, from half-way round the world, you take on board the sort of news reporting that supports a party which constantly runs our country down and works at giving its followers something to be afraid of, you will end up very afraid.
The world changes, but only superficially, and will be well known to these young people, parents, any leaders involved, and the young people themselves.
I will be frightened when our young people travel away from home. I was frightened when my children travelled in their late teens and when they moved to other countries (although that was tinged with a little envy), but the issues don't change, just the details.
