“The Sinai remains a buffer zone against major military forces, but not against the paramilitaries linked to radical Islamists who have increased their activities in the peninsula since the fall of former President Hosni Mubarak in February 2011. Last week, they attacked an Egyptian military post on the Gaza border, killing 16 Egyptian soldiers. This followed several attacks against Israeli border crossings. Morsi condemned the attack and ordered a large-scale military crackdown in the Sinai. Two problems could arise from this.
First, the Egyptians’ ability to defeat the militant Islamists depends on redefining the Camp David accords, at least informally, to allow Egypt to deploy substantial forces there (though even this might not suffice). These additional military forces might not threaten Israel immediately, but setting a precedent for a greater Egyptian military presence in the Sinai Peninsula could eventually lead to a threat.
