Netanyahu’s visit on Wednesday marks his sixth trip to the US since Trump’s return to office – more than any other world leader.

A close Trump ally, Netanyahu has long argued that Iran represents an existential security threat to Israel and has pushed the US to curb Tehran’s influence in the region.

“The Prime Minister believes that any negotiations must include limiting ballistic missiles and ending support for the Iranian axis,” Netanyahu’s office said in a statement ahead of his trip.

The visit comes as the US increases its military presence in the Middle East, with Trump warning Tehran of action if it fails to strike a nuclear deal.

On Tuesday, the president said that he was “thinking” about sending a second aircraft carrier strike group to the Middle East.

The USS Abraham Lincoln aircraft carrier was sent to the region last month after Trump threatened to strike Iran to stop a government crackdown on mass protests in which thousands of people were killed.
