Why has Israel allocated a large part of its national production to maintaining one of the most highly trained and best equipped military forces in the world?
Israel has a number of regional adversaries who have made it
clear that they intend to destroy Israel when they have the
opportunity and the ability. So Israel needs to devote an unusually
large fraction of its economy to military preparation and
readiness, in order to discourage others from pursuing their
intentions and desires in that regard, and, basically, just to
continue to exist.
