As research tells us, Jews tend to be prone to many genetic diseases, possibly caused by so much interbreeding over the last four thousand years.

Given the clear and real genetic abnormalities Jews commonly have, will Israel simply cease to exist because they'll interbreed themselves to extinction?
Not as many as the muslims who because of interbreeding have more birth defects than any other group. Will the muslims end up breeding mules that are sterile and hence lead to the demise of islam. Is this why muslims rape children from other countries so they have new blood in the gene pool.
