Israel is too small a country to develop massive sports programs.Also it's economic problems caused by Arab/Palestinian hatred, terrorism,war and sanctions and boycots make sport a luxury.
Israel has fairly good soccer teams but cannot afford international stars.It is making some waves in water sports,shooting and Paralympics due to especially many young men disabled by war,and also victims of Palestinian suicide bombing.
Most young men and women spend their best part of young adulthood in keeping Israel safe.This prevents top sport training.
The prejudice and fear of offending Muslim viewers of American and British TV from airing Israeli movies or using Israeli commentators keeps Israel out of the limelight.Most Israeli produced movies are so amateurishly anti Israel that T V stations avoid them
BBC and the Canadian Broadcaster(CBC) are blatantly anti -Israel.BBC does not even mention Israel in it's weather program.
Israel is however becoming more advanced,more middle class,and more interested in sport.This should bode well for the future .
