As the UK sanctions Israeli settlements, is the two-state solution dead?

British Foreign Secretary Ed Miliband has said the United Kingdom will sanction illegal Israeli settlements in the occupied West Bank, describing the move as “overdue” and necessary to “salvage” a two-state solution to the Israeli-Palestinian conflict.

He made the comments on Tuesday as 11 nations joined the UK in supporting or ⁠considering curbs on trade in goods with settlements that are a barrier to a future Palestinian state.

But analysts say the step is far from enough to drive momentum for Palestinian statehood, threatened by ever-expanding settlements in the West Bank and an increasingly hostile Israeli political environment.

Tahani Mustafa, a lecturer in international relations at King’s College London, told Al Jazeera the latest anti-settlement measures are “modest” and unlikely to have a significant impact on ambitions for Palestinian statehood.

“After three decades of breakneck settlement expansion, Palestinian territory is only being held together by its sinews,” said Mustafa. “If what remains is still territorially viable as a state, it is only barely so. Much more decisive action is needed to salvage the two-state solution and a durable lasting solution to the conflict.”

More than 30 years after the Oslo Accords set out a negotiating process aimed at resolving the Israeli-Palestinian conflict, the creation of a Palestinian state alongside Israel has remained the foundation of international efforts to forge peace.

But since the Oslo process began in 1993, the number of Israeli settlers in the West Bank, including occupied East Jerusalem, has ballooned from about 260,000 to more than 700,000, according to the Palestinian Bureau of Statistics, posing a glaring roadblock to the plan.

The challenge is not just the raw number of settlers, but their geographic spread. Today, many Israeli settlements are embedded deep inside West Bank areas that would be needed for a contiguous Palestinian state, including near major Palestinian urban centres such as Nablus, Salfit and Hebron.
