"As all NATO allies accept Turkey’s critical importance to the alliance, it is unfortunate that some members fail fully to appreciate certain threats to our country. Turkey maintains that the admission of Sweden and Finland entails risks for its own security and the organisation’s future. We have every right to expect those countries, which will expect NATO’s second-largest army to come to their defence under Article 5, to prevent the recruitment, fundraising and propaganda activities of the PKK, which the European Union and United States consider a terrorist entity."
