Want leverage? Then engage the Islamist regime.
The policy of isolating Hamas and applying sanctions to Gaza has been a predictable failure. Violence to both Gazans and Israelis is rising. Economic conditions are ruinous, generating anger and despair. The credibility of Palestinian Authority President Mahmoud Abbas and other pragmatic forces has been grievously damaged. The peace process is in tatters.
Meanwhile, Hamas's hold on the Gaza Strip, purportedly the principal target of the policy, has been strengthened. Since Hamas assumed full control in June 2007 the already-tight sanctions, imposed following the Islamists' January 2006 electoral victory, have been tightened further. Israel – upon which Gazans depend almost entirely for relations with the outside world – even curtailed cross-border passenger and goods traffic.
Israel has hardly been alone. The West Bank-based Palestinian Authority, seeking to undermine Hamas's standing, has done its part to cut off Gaza and prevent the normal functioning of government. Feeble protests aside, the international community has at best been a model of passivity.
The logic behind the policy was that by putting pressure on Hamas, they could prevent rocket launches into Israel. This would demonstrate to the Palestinian people that Hamas could not deliver and ought not be trusted. The hope was that the West Bank, buoyed by economic growth, a loosening of Israeli security measures, not to mention a revived peace process, would serve as an attractive countermodel. But the theory has not delivered on any of these counts.
