The safeguards for foreigners are much less than those for US citizens. For example, the NSA doesn't need to go through FISA court to spy on non-citizens. So if you store your data on a non-US server, you're probably just making it easier for them to get to it, not harder. Not to mention, most countries will pretty much cooperate with the US when it comes to intelligence. The only ones that might not are countries like Russia or China that have their own military-industrial complexes, which are just as eager to get at your data and a lot less scrupulous about using it.
