President Donald Trump will host Israeli Prime Minister Benjamin Netanyahu at the White House on Wednesday, as tensions continue to rise across the Middle East and negotiations intensify over curbing Iran's nuclear weapons programme.

Netanyahu is expected to press Trump to pursue a deal that would halt Iran's uranium enrichment, and rein in its support for proxy groups like Hamas and Hezbollah.

I will present to the president our outlook regarding the principles of these negotiations, Netanyahu told reporters before leaving for the US.

Iran has stated it will not limit uranium enrichment unless Western nations scale back sanctions that have severely strained its economy.

Netanyahu's visit marks his sixth trip to the US since Trump's return to office — more than any other world leader. A close Trump ally, he believes that Iran represents an existential security threat to Israel and has pushed the US to curb Tehran's influence in the region.

According to statements from Netanyahu's office, he asserts that any negotiations must address ballistic missile limits and end support for Iran's proxies.

This meeting occurs as the US increases its military presence in the Middle East, with Trump warning of actions against Tehran if a nuclear deal is not struck. On Tuesday, Trump indicated he was contemplating sending a second aircraft carrier strike group to the region.

Israeli officials have warned that the country reserves the right to take military action against Iran if an agreement is not reached. Experts note that Netanyahu faces pressure from his far-right government allies to leverage his rapport with Trump to secure a comprehensive US-Iran deal that aligns with Israeli security interests.

Netanyahu's discussions with Trump come amidst simultaneous talks regarding implementing further phases of the ceasefire agreement with Hamas in Gaza, marking a complex landscape of diplomatic interaction in the region.

As the situation unfolds, this meeting highlights the delicate balance of regional power dynamics and the quest for security amid ongoing geopolitical strife.
