I'm fairly certain that the Royal Navy does not have a degree requirement for any of their officers. I pretty sure they are tested on aptitude and potential and given a shot at OCS.
Neither does the Israeli Air Force.
But there are some differences that you have to keep in mind between the countries. Britain has national-level exams (A-levels) for secondary school subjects that can provide a pretty good indication of someone's aptitude, all we have are the SAT and ACT. Israel starts looking out for prospective pilots pretty early on, think early high school, and they only pick the best. And their 'flight school' lasts a lot longer, with college-level courses early in the training program.
So you really are comparing apples and oranges when you compare our officer accession programs with others.
