The people of kurdistan will have a difficult time attaining because the region spans the territory of four other states.

Sovereignty.

Explanation:

'Sovereignty' is described as the authority or power to govern or rule itself without any kind of interference or intrusion from any other sources. Such a condition or state allows the state to be self-governed or sovereign and possess the authority to make laws and control their resources on their own without the coercion of any other bodies or nations.

As per the question, the people of Kurdistan would have a struggle to attain 'sovereignty' or 'self-governance' as the region traverses over four other states and which makes it difficult to reach a mutual decision to self-govern or control their resources or make laws for them.
