All, or almost all, of Iran's military aid to Hezbollah passes through Syria, and if Syria did not cooperate Hezbollah's ability to acquire weaponry would decline dramatically. As Iran and Syria are Hezbollah's main patrons, most of Hezbollah's rockets, small arms, money, and ammunition transit through Syria. The only other efficient route for Iran to supply Hezbollah goes through Turkey, but Turkey is not aligned with Tehran and since 2006 has blocked Iranian trucks and planes from passing through its territory. Sending supplies by sea from the Iranian port of Bandar Abbas to the Syrian port of Latakia has been used in the past, but takes much longer and risks interdiction.
