Clinton told the American Jewish Committee that American negotiators needed to be "tough" and "clear-eyed" as they conduct nuclear talks but said the ongoing talks in Vienna between six world powers and Iran, represented an opportunity to reduce Iran's potential nuclear weapons-making ability. The talks are being conducted ahead of a July 20 target date for a deal.
But Clinton called it a "promising development and we need to test it to see what can be achieved. This is a time to give diplomacy space to work. If it does not, there will be opportunities to put in place additional sanctions in the future."
As she considers a potential 2016 presidential campaign, Clinton's speech to the prominent Jewish organisation represented one of her most vigorous defenses of her tenure at the State Department and highlighted her work to rein in Iran's nuclear ambitions and promote peace between Israel and the Palestinians.

Clinton presented her time at the State Department as collaboration with President Barack Obama, citing their work to prevent Iran's ability to develop nuclear weapons as an example.
She noted the recent firing of missiles at Israeli troops by militants in the Gaza Strip and warned that the Islamic militant group Hamas must reject violence and accept Israel's right to exist.
