Well, AFAIK more then 60% of today's Iraq based Kurd's factually derive from Iran, after the Shah persecuted them. Upon the Islamic Revolution in 1979 most Kurd's living then in Iraq intermixed with Iraqi Kurd's "KDPI" then thought it to be the perfect time to attack Iranian Armed forces bases and call out an independent Kurdish State - and as a result got bashed by the IRGC in 1980. Saddam refused to let them back into Iraq and instead launched his own attack onto Iran whilst allying with the KDPI.
By 1981 the KDPI had lost around 30,000 fighters and civilians, 250,000 displaced and headed back to Iraq - than later aligning with PKK forces and attacking Iraqi positions, towns and cities. Then re-surging as PJAK in the early 2000's but negotiating a peace with Tehran in 2004, thus the new PDKI taking a neutral stance towards Tehran, whilst the PJAK moved back to Iraq in 2006 and was then declared a terrorist organisation by Obama.
The very same designated terrorist organisation that TACO then contacted in Iraq - realligned and now termed CPFIK
