Israel does not feel a great need at present for more fighters. If however this is what you feel you should do and you succeed in doing it know in advance that the pay is not very high and the system not always appreciative. Nevertheless it has been done. It may be worth your while or it may not. The first step would be to contact the nearest Israeli Consulate or Jewish Agency office. They should explain whatever bureaucratic steps are needed. Chances are they will try to dissuade you but one never knows.
