I think it's fair to say that they are surprised by the Republican nominee. They are not sure how seriously to take some of his pronouncements. They're rattled by him. And for a good reason, being that as a lot of the proposals he's made display either ignorance of world affairs or a cavalier attitude, or an interest in getting Tweets and headlines instead of actually thinking true.
What it is that is required to keep America safe and secure and prosperous and what's required to keep the world on an even keel.
