Israeli Prime Minister Benjamin Netanyahu chairs the weekly cabinet meeting at the Prime Minister's office in Jerusalem, Sunday, April 15, 2018.
Netanyahu also called on Western powers to take the same approach toward preventing "terrorist states" from acquiring nuclear weapons, referring to Israel's main enemy Iran.
The U.S., U.K., and France jointly launched airstrikes on the Assad regime's alleged chemical weapons facilities in Syria earlier on Saturday.
"The American attack is an important signal to the axis of evil - Iran, Syria and Hezbollah", Gallant said.
It should be clear to Assad that his reckless efforts to acquire and use weapons of mass destruction, his disregard for worldwide law and his provision of a base for Iran and its proxies endanger Syria, said Netanyahu.
The premier said he told May that the leading source of instability in the region is Iran, and that Assad needs to understand that when he lets Iran militarily entrench itself and its proxies in Syria, he is endangering Syria and the entire region.
Punitive US-led strikes on Syria are justified because of the "murderous actions" of the Damascus government, an Israeli official said today.
On Monday seven Iranian personnel were among 14 people killed in an early-morning strike on the T-4 airbase in Syria, with regime allies Iran and Russian Federation blaming Israel for the attack.
"A year ago, I declared Israel's full support for President Trump's decision to take a stand against the use and spread of chemical weapons".
Trump's new national security adviser, John Bolton, was according to the Haaretz daily in contact with his Israeli counterpart Meir Ben Shabbat in the days ahead of the strike.
Israel has sought to avoid direct involvement in Syria's civil war, but acknowledges carrying out dozens of air strikes there to stop what it says are advanced arms deliveries to Lebanese Shiite group Hezbollah, another of its enemies.
