Obama: If Syria used chemical weapons, it's a "game changer"
The next question is about differences between Obama and Netanyahu on their approach to Iran.
At a joint press conference with Obama at the Prime Minister's Office following a lengthy meeting, Netanyahu said that with the entry of the new government, "Israel remains fully committed to peace and a solution for two states for two people."
"We extend our hands in peace and friendship to the Palestinians... let us put aside all preconditions and work together to achieve a historic compromise and put an end to the conflict," the prime minister said.
Netanyahu also emphasized that Israel "cannot cede the right to defend ourselves to others," hinting at a possible go-it-alone plan to attack Iran's nuclear program.
Addressing the same issue, Obama said he prefers to deal with the Iranian nuclear threat in a "diplomatic" manner.
He insisted that "all options remain on the table" and added that a "nuclear armed Iran would be threat to region, the world, and an existential threat to Israel."
As much as Obama prefers a diplomatic solution, he added that "Iran's leader must understand they must meet international obligations."
"I can say with confidence that Israel's security is guaranteed, and its got a great deal on its side," he said.
Obama also emphasized that the US government would continue to fund the Iron Dome missile defense system.
Obama stressed that Americas commitment to the State of Israel is a "solid obligation" and one that is "non negotiable."
"I will ensure no interruption in funding of the Iron Dome," said Obama. He added that his government would be providing $200 million this fiscal year, and would continue to work with congress to provide support for Israel. He added that the central element of lasting peace in Israel is a "strong and secure Jewish state."
Turning to Syria, Obama said that the United States was investigating whether chemical weapons had been used in Syria, and that Syrian President Bashar Assad would be held accountable if they had been.
