Israel has entered a dangerous new stage with its attacks on military targets in Syria following the downing of an Israeli F-16 jet on the weekend. It has been more than 50 years since Israel has lost a jet in combat, but the continued attacks reflect more than just revenge for the jet’s loss.

Israel has engaged in reported attacks -- said to be more than 100 -- on weapons shipments to Hezbollah in Syria over the past couple of years. The Lebanon-based, Iranian-allied Hezbollah has been critical in supporting the faltering Syrian regime of Bashar al-Assad.
