The first to develop this capacity was the Lebanese Hezbollah, in 2004. The Shiite party then managed, in 2012, to send a drone to the edge of the Israeli nuclear reactor in Dimona, in the Negev desert.
It is in the light of the wars in Syria and Iraq that the jihadists then use drones to face well-equipped armies.
But it is on the Yemeni theater that the Houthi rebels, and with them the Iranians, are putting more effective air and sea engines to the test, which can be perfected and duplicated in other theaters.
