Tony Robbins explores whether a national-service experience could give young Americans greater exposure to different communities, languages and responsibilities. He points to LDS missionary service and Israel's service system while emphasizing purpose beyond individual interests. LDS missionaries assigned a foreign language generally receive six to nine weeks of intensive preparation, according to Church materials. That training builds an initial foundation rather than instant fluency, and missionaries continue studying and using the language in the field. Israel does require military service from many eligible citizens beginning around age 18, but “everybody serves” isn't literally correct. Israeli law and policy contain exemptions and differing arrangements, while national-civil-service opportunities exist for some people exempt from the IDF.
