Likud is becoming a far-right party, because of the their refusal of a negociated solution for the israeli-palestinian conflit.
Their refusal means that heir main supporters are the settlers and religious Jews, who are the most conservative people in Israel.
The enemy of my enemy is my friend.
For the european far-right parties, the Muslims replaced the Jews and the Communists as main enemies.
So, this unholy alliance is some kind of natural.
Also, Israel is becoming tired of the lack of support from the european goverments, who prefers the petrodollars and not the shekels.
For me, as a european, Europe is becoming something very nasty.
