Honestly I think even without the "under God" part I've always thought it was kind of weird and culty.
I wish I was clever enough to come up with something witty, something like "Oh yeah, because everyone else is a thieving bastard, is that what you're saying?".
Perhaps only because they have a high likelyhood of speaking English and being able to help him? And sure, many Italians speak English, but if I needed help finding my watch, I like my odds of able to communicate with the Americans over almost any other nationality
So yes, weird an culty by design and intent.
