Giving up the Sudetenland worked out so well for the Czechs, didn’t it?
No, it didn’t. Israel’s situation with Palestine is altogether different, however. As a minority, Sudeten Germans themselves did not threaten Czechoslovakia. The problem was Nazi Germany with its overwhelming military advantage over the Czechs, using fake concern for the interests of Sudeten Germans (who weren’t being oppressed anyway) as a pretext for tearing off a piece of a neighboring country. By contrast, Israel has vast military superiority over all its neighbors. Islamic terrorists will always strike at Israel. That is a threat Israel will have to deal with on an ongoing basis, but at least it isn’t an existential threat. Demography, however, is an existential threat to Israel as a Jewish state if it insists on holding on to Judea and Samaria. Wisdom dictates that Israel safeguard its status as a Jewish state by separating itself from Palestine, which threatens to make it a majority-Muslim state.
