An example of these is the "kurt-kart theory", which asserted that Kurds were merely Turks whose name came from the "kurt-kart" sound the people made when they walked through the snow of the mountainous southeast of Turkey.[4] Turkish diplomats were taught by the National Secret Service that Kurds nor the Kurdish language exist.[5] The Turkish president Kenan Evren also claimed so during his electoral rallies.[5] Various Turkish nationalist political parties and groups in Turkey have successfully campaigned using the general anti-Kurdish sentiment of the Turkish people.[6] The Turkish state uses the threat of "terrorism" to justify military encroachment on Kurdish areas.
