Speaking at a conference of the American Israel Public Affairs Committee (AIPAC), an influential pro-Israel lobby group in the US, Blinken said on Monday that Washington “has a real national security interest in promoting normalisation” between the two countries.

“We believe that we can – and indeed we must – play an integral role in advancing it,” he said.

Blinken, who will visit Saudi Arabia this week, acknowledged that a deal may not be finalised easily. “But we remain committed to working toward that outcome, including on the trip I’m about to take this week to Jeddah and Riyadh,” he added.

The top US diplomat’s comments come amid an apparent regional realignment after Iran and Saudi Arabia agreed to re-establish their own diplomatic ties in a move expected to reduce tensions across the Middle East.

Few Arabs states have recognised Israel – a key US ally in the region – since its establishment in 1948, but former US President Donald Trump’s administration helped secure agreements to establish relations between Israel and the United Arab Emirates, Bahrain and Morocco in 2020.

Sudan also agreed to join the normalisation deals, known as the Abraham Accords.

Reporting from the White House on Monday, Al Jazeera’s Kimberly Halkett said that while it has been known that the US was pushing for Saudi Arabia and Israel to establish diplomatic ties, it was significant that Blinken explicitly called the drive a national security interest.

“And so, as a result the US sees itself as being absolutely critical in advancing the integration of Israel in the region,” she said.

Israeli officials have been calling for the normalisation deals, which would help break the country’s regional isolation, independent from its conflict with the Palestinians.

This year, Israeli Prime Minister Benjamin Netanyahu said Israel is seeking formal relations with Saudi Arabia because it could be a “giant leap towards ending the Arab-Israeli conflict”.

For their part, Saudi officials have said Riyadh is sticking by the Arab Peace Initiative, which conditions normalisation with Israel on its withdrawal from Arab territories and the establishment of a Palestinian state, as well as finding a “fair solution” to the plight of Palestinian refugees.

On Iran

On Monday, Blinken heaped praise on Israel, telling the AIPAC crowd that the US commitment to the country’s security is “non-negotiable”. The secretary of state also renewed a promise by the Biden administration to never allow Iran to obtain a nuclear weapon.

“We continue to believe that diplomacy is the best way to verifiably, effectively and sustainably prevent Iran from getting a nuclear weapon; in parallel, economic pressure and deterrence reinforce our diplomacy,” he said.

Indirect talks between Washington and Tehran to revive a 2015 nuclear deal, which saw Iran scale back its nuclear programme in exchange for the lifting of sanctions against its economy, have broken down in recent months.

Israel and AIPAC have been fierce opponents of the agreement, which Trump withdrew from unilaterally in 2018.

Efforts to restore the pact – known as the Joint Comprehensive Plan of Action (JCPOA) – have been further complicated by a crackdown on anti-government protests in Iran and Washington’s allegations that Tehran supplied Russia with drones that Moscow is using against Ukraine.

Iran denies seeking a nuclear weapon, and Israel is widely believed to have an undeclared nuclear arsenal. On Monday, Blinken said if Tehran rejects the path of diplomacy, “all options are on the table” to make sure the country does not obtain such a weapon.

Criticism of Israeli policies

Blinken also reasserted Washington’s support for a two-state solution to end the Israeli-Palestinian conflict, but he admitted that the prospects of that outcome “can feel remote”.

“We are committed to working with partners and with the parties to at least maintain a horizon of hope,” he said.

Blinken appeared to criticise some Israeli policies towards Palestinians. Israel, which prominent rights groups accuse of imposing apartheid on Palestinians, receives $3.8bn in unconditional US aid annually.

“Settlement expansion clearly presents an obstacle to the horizon of hope that we see. Likewise, any move toward annexation of the West Bank de facto or de jure; disruption of the historic status quo at the holy sites; the continuing demolitions of homes; and the evictions of families that have lived in those homes for generations damage prospects for two states,” Blinken said.

The Biden administration has been staunchly supportive of Israel, but some cracks have appeared in the relationship after the election of Netanyahu and his far-right government late last year.

On Monday, Blinken weighed in – albeit not explicitly – on the Israeli government’s judicial overhaul plan, which Netanyahu’s critics say would undermine the country’s courts and could lead to authoritarianism. The proposal has been put on hold amid domestic protests and US criticism.

“We’ll continue to express our support for core democratic principles, including a separation of powers, checks and balances, and the equal administration of justice for all citizens of Israel,” said Blinken, calling for “consensus” on any reform.

‘Racist tropes’

Blinken ended his speech on Monday by lauding and expressing gratitude for AIPAC, which spent millions of dollars to defeat progressive Democrats in US elections last year.

The organisation, which progressive activists have accused of being a “hate group”, has also faced criticism for endorsing right-wing American lawmakers who pushed to overturn Biden’s 2020 election victory.

Moreover, AIPAC regularly attacks Muslim-American congresswomen Rashida Tlaib and Ilhan Omar and has compared them to ISIL (ISIS), sparking accusations of Islamophobia.

“AIPAC has been and continues to be one of the major purveyors of Islamophobic and anti-Arab hate in the United States,” Palestinian-American comedian and activist Amer Zahr told Al Jazeera, criticising Blinken for addressing the lobbying group’s conference.

“From its inception, its unwavering support for Israel’s apartheid policies has been served with heaping spoons of racist tropes against Palestinians, Arabs and Muslims,” Zahr said.

“No one who believes in equality and justice should ever be speaking at an AIPAC conference”.
