John J. Mearsheimer in the American Conservative:
The campaign in Gaza is said to have two objectives: 1) to put an end to the rockets and mortars that Palestinians have been firing into southern Israel since it withdrew from Gaza in August 2005; 2) to restore Israel’s deterrent, which was said to be diminished by the Lebanon fiasco, by Israel’s withdrawal from Gaza, and by its inability to halt Iran’s nuclear program.
But these are not the real goals of Operation Cast Lead. The actual purpose is connected to Israel’s long-term vision of how it intends to live with millions of Palestinians in its midst. It is part of a broader strategic goal: the creation of a “Greater Israel.” Specifically, Israel’s leaders remain determined to control all of what used to be known as Mandate Palestine, which includes Gaza and the West Bank. The Palestinians would have limited autonomy in a handful of disconnected and economically crippled enclaves, one of which is Gaza. Israel would control the borders around them, movement between them, the air above and the water below them.
The key to achieving this is to inflict massive pain on the Palestinians so that they come to accept the fact that they are a defeated people and that Israel will be largely responsible for controlling their future. This strategy, which was first articulated by Ze’ev Jabotinsky in the 1920s and has heavily influenced Israeli policy since 1948, is commonly referred to as the “Iron Wall.”
What has been happening in Gaza is fully consistent with this strategy.
