Mr Ronson’s comments came a day after a poll for the JC revealed that almost 40 percent of UK Jews would “seriously consider emigrating” if Jeremy Corbyn became Prime Minister.
“In the 1950s and 1960s, the fascists had to be physically forced off our streets. That is what we did,” Mr Ronson said.
“In the 1970s and 1980s, we had to develop security against terrorists. That is what we did. In 1994, after the car bombings of the Israeli Embassy and Balfour House, CST was fully established.”
As detailed by the JC last month, Jeremy Corbyn, then a backbench MP, spent over a decade campaigning for the release of the two people convicted for their part in the 1994 car bombings, claiming there had been “a miscarriage of justice”.
Mr Ronson added: “CST has spent millions of pounds providing security for Jewish communities across the country.
"If you lead any sort of Jewish life, from school to synagogue to old age home, CST is helping to secure you and your family.
"I am proud of what we have built, and I thank the thousands of Jewish men and women who have helped make it a reality.”
