The truth is that Russia is the whore of arms sales. They denied that these were Russian missiles when Israel brought them whole Kornets with their markings captured from Hezbo. But as the Israel Bashers say: What goes around, comes around so Hezbo is probably going to get these weapons as well, but in the big scheme of things it would be a mere nuisance for the Israeli army but will not change the big picture. In military terms, it would mean that Israel will have to take more stringent anti-measures which means that more Hezbanese will die. So go cheer this, Israel bashers. As you say: What goes around, comes around.
