Jerusalem: Israeli Prime Minister Benjamin Netanyahu defended on Thursday his high-profile campaign to defeat the Iran nuclear deal after President Barack Obama secured enough backing to keep Congress from blocking it.
Netanyahu has repeatedly spoken out strongly against the agreement between Iran and six major powers aimed at rolling back the Islamic republic's nuclear programme, even appearing before Congress in March.
On Wednesday, Obama earned sufficient backing in Congress to uphold his veto should lawmakers pass a resolution that disapproves the deal.
Netanyahu, whose political opponents accuse him of damaging Israel's relationship with its key US ally, said Thursday it had been important for him to highlight the Jewish state's concerns.
The right-wing prime minister has regularly argued that the deal would not block Iran's path to nuclear weapons.
He has also said that lifting sanctions under the agreement would allow Iran to further back proxy militants in the Middle East, including Israeli enemies Hezbollah and Hamas.
"It's important to reach American public opinion with the fact that Iran is the US's enemy -- it announces that openly -- and Israel is an ally of the US," Netanyahu said.
"This understanding has important ramifications on our security's future," he told foreign ministry employees.
On Wednesday, US Senate Democrat Barbara Mikulski announced her support, giving the deal 34 backers in the 100-member Senate -- the magic number needed to uphold a certain Obama veto should Congress pass a resolution against the deal.
Netanyahu's campaign against the deal worsened his already strained relations with Obama.
In his today's remarks, Netanyahu noted "the close connections we have with traditional states, first and foremost the United States, even in the face of disagreements - and those exist."
Isaac Herzog, leader of the opposition Labour party, said that while he thought the deal was bad, once it was done, Netanyahu should have switched focus to Israel's security needs.
The United States currently grants Israel some USD 3 billion (2.7 billion euros) in military aid yearly outside of spending on other projects, such as assistance in developing the country's Iron Dome missile defence system.
There has been talk of further assistance to compensate for Israel's concerns related to the deal.
"Netanyahu is continuing to bear a grudge instead of working with the Americans on the big issues (of security) -- and in the end, the ones to pay the price will be us," Herzog told army radio.
Israel is believed to be the only country in the Middle East with atomic bombs, although it has never confirmed it.
