As soon as it became clear on Sunday that there would be regime change in neighboring Syria, Israel began a sweeping aerial campaign.

By Tuesday, at least 350 airstrikes had leveled military assets across Syria, taking out the Navy, fighter jets, drones, tanks, air-defense systems, weapons plants and a wide array of missiles and rockets, according to the Israeli military.

Israeli officials said they were destroying weapons and military facilities to keep them out of the hands of Islamist extremists. The rebel group that led the toppling of the president, Bashar al-Assad, was formerly linked to Al Qaeda and is still designated as a terrorist group by the United States and the United Nations.

“We have no intention to meddle in Syria’s internal affairs, but we certainly intend to do whatever is needed to guarantee our security,” Prime Minister Benjamin Netanyahu of Israel said on Tuesday.

The Israeli campaign over the past two days has been exceptional in force and scope, trying to ensure that whoever ends up in power in Syria will be significantly disarmed.

It followed months of intensified Israeli airstrikes on Syria, including on weapons depots belonging to Iran and Hezbollah. But the large-scale bombings this week have been far more comprehensive and devastating to Syria’s military capabilities, analysts said.
