Brief Explanations:

The Kurds' pursuit of ethnic - related goals has led to tensions. Nationalism often involves a group's assertion of its identity and rights, which can cause conflicts in multi - ethnic regions like Southwest Asia. Ethnic cleansing is a violent and illegal act; diversity is not something that causes conflict in this context; unification is not the most accurate term here as it implies bringing separate entities together in a more comprehensive way. Nationalism best describes the Kurds' quest that has led to tension.
