Find me any definition that is or is not Europe. If you can draw a line between the Mediterranean, Baltic and Atlantic, sure. Britain, Ireland and associated islands? Iceland? Greenland? Scandinavia? What about to the East over land? Is Russia European? How much of it?

The definition of “Europe” is useless because the definition of “continent” is useless. Australia: does the continent of Australia include Tasmania and/or New Zealand? Some folks claim both Americas are one continent because they were connected at the Isthmus until we sawed Panama in half. If we classify them separately, where does North America end and South America begin? My middle school taught that North America only had three nations on it, Canada, USA and Mexico. Mexico is on North America but Belize isn’t? What about Greenland? Africa: Madagascar? The Arabian peninsula? Asia: Japan? What about India? Is the “subcontinent” part of Asia?

Europe is the least convincing of them all. Pretty much nowhere else do you have to start mentioning “culture” when drawing a border between continents.

III. CONDITIONS OF ACCESSION a) The European State

The sole material condition laid down by Article O of the TEU is that the applicant must be a ‘European State’. There is no unequivocal interpretation of that criterion. It can be read equally well in geographical, cultural or political terms.

In 1987 an application to become a Member of the Communities was received from Morocco. The application was rejected by the Council on the grounds that Morocco was not a European State ( 7). In the case of Turkey, Article 28 of the Association Agreement signed in 1963 incudes the option of Turkey’s eventually acceding to the Communities. Turkey in fact lodged an application to accede on 14 April 1987. Historically, Turkey has formed part of the so-called ‘European concert’. Although part of Turkey’s territory is located geographically in Asia, Parliament, the Council and the Commission have confirmed Turkey’s eligibility ( 8). This example shows that the term ‘European State’ need not be interpreted in a strictly geographical sense. It is at all events a criterion subject to political assessment.

No no no. That’s not how being corrected on the internet works! You have to be wrong, AND be certain that you’re right! THEN someone can come along and say “Actually…”
