While some will object to any Nazi comparison, but on ecan't help remembering that German rocket scientists were planning to take mankind to the stars. They did, to some extent; the first photographs of the earth from orbit were made from modified V2 rockets. Slave labour camps and the all the crimes of the Hitler era were, for some of these scientifics, completely justified by the promise of huge scientific advances, which they were sure in the end would benefit all mankind.
Another thing, when you hear Israelis and their supporters like Taft talking in this vein, is to remind oneself that Israel is essentially a colonial project. Zionists themselves often referred to the 'colonization of Palestine' before WW2. Throughout the imperial/colonial, many of Europes' greatest technological advances were made either in the colonies or because of the colonies. The richest 'Europeans' were often those who lived abroad. Think of people like Elihu Yale, who made his money in India, or Cecil Rhodes in Africa; the richest French Dutch English etc men in the 17th & 18th & 19th centuries usually made their money in the colonies. In mid 17th century the richest English men often made their money in either Barbados or Jamaica, on the backs of course of slave labour.
Israel is essentially the last European colony, and its wealth and success, like all colonies, has come largely at the expense of the indigenous people.
