In the long run it is not a viable country, I'm not talking about any wars or possible wars either, but just simple demographics. The Arab/Palestinian population is growing faster than the Israeli/Jewish population, and the fastest growing demographic of the Jewish population is the Orthodox Jews. They are not obliged to serve in the Israeli military and some don't believe Israel should be a separate nation (as it is a right reserved for god's judgement only, not man's). Simply from a demographic standpoint, the way things are cannot be sustained exist in Israel, regardless of wars or extremism.
