Shmuel (Seth) Sackett (Hebrew: שמואל סקט, born 1961 in Middle Village, Queens[1]) is a Religious Zionist leader.
He co-founded both the Zo Artzeinu and Manhigut Yehudit ("Jewish Leadership") political movements in Israel.
He worked in Wall Street's Financial District before making Aliyah to Israel and settling in the West Bank in 1990.
Sackett had been a member of the JDL in the 1970s, and a loyal follower of Kach leader Rabbi Meir Kahane in the United States.
Sackett and Feiglin shared some of Meir Kahane's goals, such as the ethnic cleansing of Palestinians within Israel and the West Bank, but wished to achieve them via non-violent methods.
