"Anti-Semitism certainly has not disappeared. But there is much we can do to fight back. World leaders need to unequivocally condemn anti-Semitism wherever it is found,’’ Israeli Prime Minister Benjamin Netanyahu said in an address broadcast by video to the Jewish Policy Institute Conference in Jerusalem.

He thanked US President Donald Trump and Vice President Mike Pence ‘’for having taken a strong stance in condemning anti-Semitism,’’ in a reference to the spate f anti-Semitic incidents across the United States.

He urged European leaders to follo suite. ‘’Most of them have done it and this is what we must demand from governments around the world because Jews around the world should not live in fear," Netanyahu said.

“Israel’s influence is expanding as never before. And as it expands, we are garnering allies for our people everywhere,” said Netanyahu. The entire world is coming to Israel because of our expertise in technology and in countering terrorism. And this is why I’ve never been more hopeful about the Jewish future,’’ he also said.

“Israel is stronger than ever. Our impact in the world is ever expanding,” he stressed, adding, “100 years ago, on the eve of the Balfour declaration, people asked what to do about what they called ‘the Jewish question’. Well, 100 years later, the answer is clear.

“Israel is the answer. So today I ask all of you to do two things, only two things: support Israel and fight anti-Semitism. They are one and the same,” said the Prime Minister.

Earlier this week President Trump began his address to a special joint session of Congress by condemning the recent acts of anti-Semitism.

"Recent threats targeting Jewish community centers and vandalism of Jewish cemeteries, as well as last week's shooting in Kansas City, remind us that while we may be a nation divided on policies, we are a country that stands united in condemning hate and evil in all its forms," he said.

On Monday, at least 10 Jewish community centers and Jewish day schools across the United States received bomb threats, the fifth wave of such threats in less than two months.

In addition, two Jewish cemeteries have been vandalized in recent weeks. Nearly 200 headstones were knocked over in a Jewish cemetery near St. Louis.
