It is understandable that one might somehow feel justified in such thinking. It may seem to some that there is no other way to compel Hamas to comply with international standards. In all actions one must weigh the commission of an act against the repercussions that are possible. One must, of course, also consider the application of appropriate Jewish teachings. There are, naturally, a few relevant texts that could guide us. There is also the Geneva Convention’s dictates regarding prisoners of war, which if Israel is a signatory of that document, then we must also abide by these rulings.
At first blush, some may recoil from even the consideration of such reciprocal thinking. After all, we carelessly teach our children that “two wrongs never make a right.” But know that as seemingly colloquial as this saying is, this principle stands out clearly in Jewish teachings. We learn this general rule from Mishnah Shekalim 3:2, which states that “One must behave before all creatures as one must before God, as it is written in Torah (Numbers 32:22) ‘You shall be clean (guiltless) before the Eternal and Israel,’ as it says (Proverbs 3:4) ‘So will you find grace and right thinking in the sight of God and humanity.’” Or to use a dictum from our sage Hillel, “That which is hateful to you do not do to your neighbor” (Shabbat 31a).
On the other hand, some could argue that jailed Hamas militants fall into the category of “rodef,” that is, one who pursues another with intent to murder; the Talmud states in Berakhot 62b that “If someone is coming to kill you, rise up first and kill this person.” Similar to all many laws, however, this teaching comes with restrictions. The one most pertinent to your question may be that one must do the least harm necessary to stop the rodef from murdering: In Sanhedrin 57a, we learn that one who kills (my emphasis) a rodef when breaking a limb would have sufficed is liable for capital punishment.
According to Rabbi Jill Jacobs, “Some halakhic authorities have argued that a POW or suspected terrorist may be considered a rodef, and may therefore be harmed as a means of extracting information that has the potential to save lives.”

But it is also important to cite the decision of Israel’s Supreme Court regarding the application of this guideline while weighing it against other democratic principles. In 1999, the Court stated: “Although a democracy must often fight with one hand tied behind its back, it nonetheless has the upper hand. Preserving the Rule of Law and recognition of an individual's liberty constitutes an important component in its understanding of security. At the end of the day, they strengthen its spirit and its strength and allow it to overcome its difficulties.”

The Geneva Convention relating to prisoners of war takes great pains to define “prisoners of war,” and to mandate certain behavior toward them. Article 13 states this: “Prisoners of war must at all times be humanely treated. Any unlawful act or omission by the Detaining Power causing death or seriously endangering the health of a prisoner of war in its custody is prohibited, and will be regarded as a serious breach…prisoners of war must at all times be protected, particularly against acts of violence or intimidation and against insults and public curiosity. Measures of reprisal against prisoners of war are prohibited.”
Article 14 may also contain important guidelines for us to consider: “Prisoners of war are entitled in all circumstances to respect for their persons and their honour…Prisoners of war shall retain the full civil capacity which they enjoyed at the time of their capture. The Detaining Power may not restrict the exercise, either within or without its own territory, of the rights such capacity confers except in so far as the captivity requires."
In the final analysis, one must consider the specific privileges that were removed by virtue of the Prime Minister’s act, and evaluate whether having eliminated them results in a violation of the Geneva Convention, relevant Jewish teachings, or a ruling of the Israeli Supreme Court. I do not know specifically which privileges you speak about, so I cannot make that determination. However, one must use Jewish principles and the guidance of our tradition – and the good sense that God gave us – to determine any particular course of action. Whether you feel “justified” by the Prime Minister’s actions is up to you.
