is no longer a party just for northern Kurdistan: Today it also impacts significantly on the other parts of Kurdistan – something the KDP cannot tolerate”.

Therefore we should not see the Kurds as a solid group, because they have their differences and Erdogan is trying to make it harder for them to unite, by having Iraqi Kurds to depend on him for exporting their oil, through the Turkish port of Ceyhan in the Mediterranean Sea. If Iraqi Kurdistan was an independent country, it would be approximately the 10th richest region in the world in terms of oil reserves (not oil production). The red diagram in the following map is a very rough sketch of Kurdistan, and the export route for Kurdish oil in Northern Iraq.
However even though the Kurds are not as solid as a rock, it seems that the conditions for the establishment of an independent Kurdistan are very favorable since the Western countries see them very positively.
The Kurds have also Israel on their side. The Kurds are for Israel a natural ally, because the Kurds are not Arabs, they are not Persians, they are not Turks, and they are moderate Muslims. Ocalan’s PKK is a Marxist Leninist party, and religion should not be important at all.
Moreover the Kurds can take lands, and therefore weaken, four of Israel’s greatest enemies i.e. Iran, Syria, Turkey, Iraq. That’s the reason Israel is openly asking for an independent Kurdistan. For the Kurds too, even though they are Muslims in a Muslim region, Israel should be a natural ally, since the countries that surround them do not see an independent Kurdistan positively. And if in the past, the excellent relations between Israel and Turkey prevented Israel to openly support an independent Kurdistan, now there is nothing to stop them.
At the following two articles, one from the Guardian, titled “Israel's prime minister backs Kurdish independence”, June 2014, and one from Reuters, titled “Israel's Netanyahu calls for supporting Kurdish independence”, June 2014, you can read that the Israeli Prime Minister Netanyahu openly asks for Kurdish independence and Kurdish statehood.
