The Turkish invasion of cyprus, the greeks respond by declaring full-scale war.NATO seeing turks as the aggressors put an arms embargo on turkey to force them to withdraw.Not pleased with the response they get, Turkey leaves NATO and asks USSR for military aid.
Implications ? Do the turks really have a lot to gain from going in the soviet camp ( their historical enemies) ? but in the past on occasions they have turned to them for help ( like in the greco-turkish war of 1922).
Soviets will be more than willing to help expansionists turkish ambitions if it weakens NATO
Turks will see little benefit in staying in NATO if it supports its historical enemy Greece
