The implication of this move could be Israeli assistance in promoting international recognition of the Armenian holocaust, a measure that would gravely harm Turkey. Israel may also back Armenia in its dispute vis-à-vis Turkey over control of Mount Ararat.
Lieberman is also planning to set meetings with the heads of Kurdish rebel group PKK in Europe in order to "cooperate with them and boost them in every possible area." In these meetings, the Kurds may ask Israel for military aid in the form of training and arms supplies, a move that would constitute a major anti-Turkish position should it materialize.
