This week, Alpher discusses the strategic significance for Israel of last week’s sweeping Islamist attacks on Egyptian army installations in Sinai, near the border with Israel; the regional implications, shared by Israel with some of its neighbors and with Europe, Russia and the United States; defines Israel’s dilemma in strategic terms, and what the ramifications are; how West Bank-based Hamas and lone-wolf terrorism affect Israel’s relations with Palestinian Authority leader Mahmoud Abbas; and what this portends for the prospect of an Israeli-Palestinian peace process.
