CHANGE: Israeli Millennials, Tilting Right, Helped Elect Netanyahu.

Like most Israeli millennials, Tal Shushan is a proud right-wing voter.

Benjamin Netanyahu has been Israeli prime minister for more than half Ms. Shushan’s 23 years. During that time, the country feels more secure than ever, she says.

“He knows how to defend his country,” said Ms. Shushan, who recently left the military and voted for Mr. Netanyahu’s Likud party Tuesday.

Israel’s young people have helped move the country right during the past decade, supporting Mr. Netanyahu’s Likud and smaller parties that help him form governing majorities. It is likely to be a lasting shift because of the rising ultra-Orthodox population, which tends to vote for religious parties that align with Likud in governments.

Born close to or after the 1993 Oslo peace accords between the Israelis and Palestinians, and coming of age during a wave of violence known as the second Palestinian intifada, Israel’s millennials take a harder line on security and peace than older generations.

“The hope or yearning for peace is foreign to them,” said Yohanan Plesner, president of the Israel Democracy Institute, a think tank in Jerusalem.

Do not yearn for “peace.” Work for victory.
