Even whilst the US engages in intensive efforts to revive final status negotiations, lack of progress in recent years and apparent gaps between Israeli and Palestinian leaders are causing some to claim that the window is closing on a two state solution. In this briefing Dr Toby Greene makes the case that there is no alternative one state ‘solution’ to the Israeli Palestinian conflict, and that whilst adverse trends are making a two-state agreement harder to achieve, none of these are fatal to it. Although scepticism abounds, the briefing points out that majorities on both sides still favour in principle a two-state solution, and looks at ways in which third parties can support the process.
