In the late 1970s, while she was in the 11th grade, Strook gradually became more religious; she eventually became a ba'alat teshuva and embraced Orthodox Judaism.

In 2007, Strook's son Zvi was convicted of abusing a Palestinian boy and killing a young goat, and spent thirty months in an Israeli prison as a result.

In response to the ruling, Strook stated that, "Unlike the Court, who preferred to believe the Arab witnesses, we are sure of Zvi's innocence, and are hurting from the success of his haters and would assist him to deal with the difficult sentence imposed on him".

[citation needed] For the 2021 elections, Strook was placed fifth on Religious Zionist Party's list,[10] and returned to the Knesset, as the alliance won six seats.

[12] Strook criticized Israeli security officials who called attacks against Palestinians by Jewish settlers in the West Bank "terrorism".

[14] In May 2024, Strook opposed a potential agreement for a ceasefire in the Israel-Hamas War, which proposed Israel halting hostilities in exchange for Hamas releasing Israeli hostages.
