The following essay suggests responses that the State of Israel – not necessarily the IDF – should provide to five types of problems presented elsewhere in this volume: (a) the problem of Lebanon; (b) the high trajectory threat, which although it relates to Lebanon is a more general threat, as it also appears from the Gaza Strip, Syria, and Iran, and harbors great damage potential that may not have been presented in full in the preceding discussions; (c) what is the right way of prosecuting a war with Syria; (d) coping with the Iranian nuclear threat; and (e) how does one prepare for peace agreements and lines that cannot be crossed in these agreements, both with the Palestinians and the Syrians.
