I consistently say that one needs to always be optimistic. Optimists win; pessimists make headlines. Optimism is not merely a mood—it’s, and must be, expressed through action.

Whether by coincidence or not, on the morning after the American B2 bomber strike in Iran, I completed the purchase of another tract of agricultural land in the Land of Israel, the culmination of almost a year’s work and negotiation. This is land that young men and women will till; land that will yield blue‑and‑white crops; land whose value and importance will rise as the population of Israel grows. I am optimistic.

As I said in my CNBC interview last week, at our fund—Aleph—we committed only a few days ago to invest in a new company (we submitted a term sheet last week). The CEO, one of the founders, has spent the past two weeks on very intensive reserve duty, yet he is busy building the future. He is optimistic—very optimistic—and we stand with him.

There is a baby boom in Israel, particularly among reservists and other groups, and I believe this trend will continue to strengthen. The same people who have gone back again and again over the past two years to fight for our security are bringing more children into the world.

Despite the hardship, despite the challenges of recent years, despite hundreds of days in Gaza, Lebanon, Syria, and along the borders with Egypt and Jordan, and, most recently, in Iran, they are optimistic. Their spouses are optimistic. And we stand alongside them, shoulder to shoulder.

Therefore, specifically during this historic week, I would like to call on Israelis who have lived overseas for years or who have recently relocated to the UK, Barcelona, Madrid, Cyprus, Amsterdam, Thailand, the United States, and elsewhere.

The future of the Jewish people is here

Specifically, this week I want to call out to hi‑tech professionals, scientists, academics, and businesspeople: Come home! Return Home! “We should go up at once” (Numbers 13:30). These are historic days. The past years were challenging, but the time to build has come. A time of revival, of reconstitution, has arrived. A time of renewal is here. Be optimistic—through action—and we will stand at your side.

To our brethren, the Jews of the diaspora, in the United States, France, and England, I call on all of you: make Aliyah. The future of the Jewish people is here, in the Land of Israel. Bring your talent, your faith, and your energy to the land of our fathers.

Do not stand and watch from the side while the winds of history summon you. Join the Israeli optimism and resilience. “The land is an exceedingly good land” (Numbers 14:7). Our people are good, strong, and creative. Please come.
