A country deciding to join something like the EU should require a super majority, not a mere majority of those voting. It's a major obligation for everyone, and requiring a super majority helps ensure that the decision is not one that is due to a passing fancy. The US Constitution recognizes this by requiring a 2/3rds vote in the Senate for treaties, as well as signature of the President. The practice of having countries conduct votes on EU membership until a vote passes with a simple majority - this whole Brexit thing shows what a folly that is. Putting a bar of a 2/3rds vote for entrance, and for significant new treaties would help ensure there is actual buy in, and not just simple politicking.
