Who, besides you, says "It is not proven that Iran is arming Hezbollah and Hamas"

Iran says so
Hamas says so
Hezboallah says so


Are you saying they are a bunch of liars???

Please show me, from sources that represent Iran, Hamas, and Hezbollah, documentation that they are being armed by Iran. I have seen representative of all three groups saying that Iran is not arming Hamas or Hezbollah.
