Netanyahu said Israel "had stayed on the sidelines of the Syrian war so far", acting only to stop transfers of advanced weapons bound for Hezbollah, a Shiite political party that serves as Iran's proxy militia in Lebanon.
"He claims Iran is fighting extremism, and he argues the conflict in the Middle East won't be resolved by a military solution", Netanyahu said.
The prime minister has always been concerned about Iran's influence in the Middle East and warned that the country's power is growing as militant groups like ISIS lose territory.
Netanyahu's comments came just over a week after Israel shot down an Iranian drone that had penetrated its airspace and launched an attack on Iranian targets in Syria in response.
"This is a very unsafe development for our region".
In Munich, where 11 Israeli athletes were killed by Islamic terrorists in 1972, Netanyahu suggested the Obama administration's 2015 nuclear deal with Iran was like the 1938 Munich Pact that appeased the Nazis and led to World War II.

Kerry dismissed Netanyahu's assertion that Iran would be on its way to having a nuclear arsenal in 10 years.
Saying he had "a message to the tyrants of Tehran" during a speech at the Munich Security Conference, he warned: "Do not test Israel's resolve". John Kerry, the former USA secretary of state who helped clinch the agreement, said it was wrong to assume Iran would obtain a nuclear weapon as soon as the 15-year scope of the deal ends.
Netanyahu is not a suspect in the Bezeq case, but the investigation is inching closer to him just days after police recommended he be charged with bribery and breach of trust in two other corruption cases.
On Sunday evening, Netanyahu denounced the investigation.
