Not to mention, Kurds and Iranians get along quite well. Kurdish is an official language in Iran and in any case it's apparently not too difficult to understand each others' languages.
Turkish Kurdistan is also a lot different from Iraqi and Syrian Kurdistan. The Kurds in Turkey are a community which is living not just in a neatly-defined geographical area but all throughout the country. The biggest "Kurdish" city is Istanbul. All parties in the national assembly have Kurdish MPs, AKP most of them. The parties that define themselves as Kurdish serve only a lesser part of the Kurdish community, and in any case they are not comparable in any way to the two "state parties" of Barzani and Talabani (KDP and PUK) that run Iraqi Kurdistan and serve as the twin political manifestation of their societies, similar (in scope but not in ideology) to the Communist Parties that ran the socialist nations of old times, with youth organizations, party militias, and social organizations that are enmeshed on every layer of society.
Turkey is, for all intents and purposes, a much more individualist and (socially) modern country than Iraq or Syria where everything is about group identities and group politics. In Iraq and Syria, the individual is nothing (politically / socially) and will be preyed upon if he's not part of a clan or subordinates himself in other ways to a group. While in Turkey different values have taken root, and you have more individualism. (Although by western European standards it's still a very clannish place with much less individualism than you or me might be used to IMHO.)
Therefore Turkish Kurdistan and Iraqi Kurdistan can't really be treated as parts of the same whole. They are only like than on Wikipedia maps.
