Israeli Prime Minister Benjamin Netanyahu pledged Saturday to annex Jewish settlements in the occupied West Bank if re-elected, a dramatic policy shift apparently aimed at rallying his nationalist base in the final stretch of the tight race.

Netanyahu has promoted Jewish settlement expansion in his four terms as prime minister, but until now refrained from presenting a detailed vision for the West Bank, seen by the Palestinians as the heartland of a future state.

An Israeli annexation of large parts of the West Bank is bound to snuff out any last flicker of hope for an Israeli-Palestinian deal on the terms of a Palestinian state on lands Israel captured in 1967.

A so-called two-state solution has long been the preferred option of most of the international community. However, intermittent US mediation between Israelis and Palestinians ran aground after President Donald Trump recognized Jerusalem as Israel's capital early in his term. The Palestinians, who seek Israeli-annexed east Jerusalem as their capital, suspended contact with the US.

More recently, Trump recognized Israeli sovereignty over the Golan Heights, a plateau Israel captured from Syria in 1967. The move was viewed in Israel as a political gift by Trump to Netanyahu who is being challenged by former military chief Benny Gantz.

Polls have indicated a close race, though Netanyahu's Likud Party is expected to have a better chance than Gantz's Blue and White slate to form a ruling coalition. Polls forecast more than 60 out of 120 parliament seats for the Likud and smaller right-wing and ultra-Orthodox Jewish parties

On Saturday, Netanyahu gave an interview to Israel's Channel 12 TV at the top of the prime-time newscast. Netanyahu portrayed the US policy shifts on Jerusalem and the Golan Heights as his achievements, saying he had managed to persuade Trump to take these steps.

Netanyahu pledged that he would not dismantle a single Jewish settlement and that Israel would retain control of the territory west of the Jordan River — the West Bank. More than 600,000 Israelis now live on war-won lands, two-thirds in the West Bank.

The interviewer asked why he hadn't annexed some of the larger settlements during his current term. "The question you are asking is an interesting question, whether we will move to the next stage and the answer is yes," he said, adding that the next term in office would be fateful. "We will move to the next stage, the imposing of Israeli sovereignty."

“I will impose sovereignty, but I will not distinguish between settlement blocs and isolated settlements," he said. "From my perspective, any point of settlement is Israeli, and we have responsibility, as the Israeli government. I will not uproot anyone, and I will not transfer sovereignty to the Palestinians.

In any partition deal, the more isolated Jewish settlements would likely have to be uprooted to create a viable Palestinian state.

Saeb Erekat, a veteran former Palestinian negotiator, said he held the international community, especially the Trump administration, responsible for Israel's policies.

"Israel will continue to brazenly violate international law for as long as the international community will continue to reward Israel with impunity, particularly with the Trump administration's support and endorsement of Israel's violation of the national and human rights of the people of Palestine," he said in a statement.
