I've remembered St. Helena and I thought of it as one of the safest locations if ever a war will start but it's far from the main land. It's a remote island and has got mountains on it.
But, it's surrounded by bodies of water so, let's say you're safe from war but you're not safe from natural calamities.
Well, I just want to visit there someday.

St Helena is a British territory, and not far from
Ascension Island, which has a joint UK/US military presence... so even tropical islands can be military targets.
