The Jewish diaspora which was the nation of Israel for centuries actually did and does contribute significantly
to world science and engineering. Those Israelis from the ex-USSR were not just some random thieves, they
were key to the development of those technologies. Naturally this does not imply Russians made no contribution
and were nothing but "bydlo".
The reason that you don't hear much about Jewish scientists in Europe during the 1500s, 1600s, etc. is because
it was not a good idea to advertise being Jewish. I think it was common conversion to Christianity during this
period in order to be able to socially advance. And Hollywood is a myth factory.
The above does not imply I support what has been done to Palestinians. Even if this land was Israeli two thousand
years ago, that does not give automatic rights to return. That is the nature of human reality. You have to fight
for your land and you lose it once you leave. It is tragic at the the time, but it is another tragedy trying to reclaim
it thousands of years later and kicking out the inhabitants.
