1. If you base the Israeli claim to Eretz Yisrael on the United Nations (rather than on the basis of Torah, which raises many issues since Torah was clearly given in order to facilitate doing mitsvos, not building a secular state), then the United Nations can simply repeal its resolution and pick a different one. In addition, the British claim to Palestine was purely based on conquest, and if the Brits had a right by conquest, all the Arabs have to do is conquer and its there’s pure and simple. Over the last 70 years, international law has evolved to the point that no country can claim a right by virtue of conquest – and you’ll note that no country has added territory since the end of World War II by conquest unless they can assert the people support them.
2. My comments on the army were based on being in a regular (i.e. secular) unit. If the army keeps religious soldiers in separate religious units it will minimize the immediate problems but create a discrimination issue that will become a “time bomb.” Problems include fast days (army rules exempt soldiers from working, but units villify those who don’t work on fast days), davening schedules (soldiers are released for davening rather than davening being part of the schedule), disputes of kashruth and the fact that most kitchen personnel are hiloni, behavior of male and female hiloni soldiers in ways we can not discuss (it was with a good basis that some gedolim compared the army to a “Beis Busha” and discussed with female conscripts were considered to be a “shevuyah”). Note the recent incident where some frum Dati Leumi officer candidates were disqualified from becoming officers because they refuse to listen to women singing (i.e. refuse to be present with naked women). Unless the hilonim agree to have the whole army be run based on the parameters of hareidi society, allowing for some separate “Nahal hiloni” units- there will be a serious problem.
3. “National service” is supported only by religious Jews who want to serve but hold they are prohibited (being female). Unless you recognize full time learning as “national service” , it has no support from the hareidi community except as an alternative to military service for hareidi baal ha-battim who don’t want to serve in the army (an option that has been rejected)
4. The government has occasionally arrested hareidim for not serving, and the hiloni press anticpates that hareidi who refuse to serve in the army will go to prison. Unless the medinah agrees to regard hareidim as religious objectors, with the penalty limited to loss of some government fund (similar to what happens to Israeli Muslims who don’t serve in the army, and no worse), a very serious crisis is brewing.
