AbstractTurkey has emerged as a major actor in the Middle East over the last decade, since the ruling party AKP came to power in 2002. Turkey is now playing a mediation role in regional conflicts and has been speaking out loudly on sensitive issues such as the Iranian nuclear program and the Palestinian- Israeli conflict. Furthermore, Turkey has established close ties with the Arab world which has suffered the relationship with its long-time ally Israel. This new presence in Middle East has been criticized by Turkey's allies in west. Critics argue that the country is about to abandon its former western relationship and strengthen their ties with the Arab world instead.This thesis has two main purposes.
