Joseph- I do not know the sugya that well and I certainly don’t have sources for you. But, I do not know of too many poskim that rule a) it is assur to live in Eretz Yisroel today because it’s more dangerous than the USA, b) it is assur for a soldier to serve in Tzahal because he puts his life at risk to defend the borders of Medinas Yisroel and its inhabitants (though there may be other reasons why serving in Tzahal is problematic), or c) that the War of Independence and the Six Day War were fought be’issur because Jewish lives were at risk.
Maybe there are a few opinions that say those things and I wouldn’t be surprised if you’re able to quote them, but that doesn’t seem to be the opinion of the Dati LeUmi Gedolim and Poskim, and I don’t think it is the opinion of many Charedi Gedolim and Poskim.
