Iran wanted to attack Afghanistan in '98 after nine IRGC "diplomats" supporting Shite rebels over there were captured and killed but the "vaunted" Iranian forces would have gotten their backsides kicked hard by the Taliban mujahadeen there so they stayed out. Also, boisterous Iran is too cowardly to attack any nation directly so they instead steal their people's wealth of natural resources and channel it to highly paid militant proxies to do their fighting for them. With as much as the Iranian Regime hates Israel and boasts against it, they have not dared to send over even one of their IRGC Al Quds commandos over Israel's border with Lebanon to challenge the IDF who is also growing bored awaiting Ahmadinejad's boasts about sending a naval fleet to challenge Israel's necessary blockade of Gaza.
