Israel has been carrying out a campaign-between-the-wars since 2013 to prevent Iran and its proxies, including Hezbollah, from obtaining advanced weapons to use against the Jewish state and from entrenching themselves in Syria.
The attacks have three main purposes.
To diminish Iranian capabilities being shipped to Hezbollah and other Iranian militias working to open a low-intensity military front threatening Israel’s northern border;
To maintain Israel’s freedom of action and air supremacy in its neighborhood and the Middle East in general by minimizing Syrian military capabilities, more specifically anti-aircraft missile sites and their support systems; and
To send a message of deterrence to three main actors in the region: Assad’s regime, Iran and its emissaries, and Russia.
