I have never listened to Gabriela Lickso on Israel National Radio. I think she is new there... It took me a while to get past her thick Hungarian accent but my boss at work is Hungarian and I have grown accustomed to the accent.
I am about 10 minutes into the talk and it sounds like a pretty good background on the topic...
