Russian, Syrian and Iranian rockets were found in abundance, both in Lebanon (intact, or destroyed by Israeli bombs, or as fragments in Israel). Although most of the world prefers to change the subject, Israel will continue to ask why these nations sold all these weapons to a terrorist organization.
Israel collected ample evidence that Iran and Syria had supplied Hizbollah with anti-tank guided missiles (ATGM) and rockets. The evidence was in the form of many captured weapons (often with data plates giving serial numbers and nation of manufacture.) In addition to complete weapons, there were many fragments found, collected, and carried back to Israel. The latest Russian ATGM (the 9M133 Kornet) was found in great numbers. These had been openly sold to Syria back in 2002. If was feared that some might show up in Iraq, but they never did. Iran apparently supplied hundreds of its version of the older Russian 9M113 Konkurs. This is a 32 pound, wire guided missile design from the 1970s.
