is that if Hezbollah has recieved deliveries of a Scud missile, it's current stance is that Lebanon will have to be attacked, as a Scud mssile is WMD capable with being armed with either a chemical or a biological warhead. Hence the phrase in this article. "Israel sees the missiles as symbolically significant rather than practically important. Some of Hezbollah's rockets are more accurate and their warheads could be almost as deadly." Seems intended to calm domestic opinion, rather than portraying the truth of this particular situation. What Israel calls a terrorist entity may have access to weapons of mass destruction and the means to deliver them. This could be a real problem in the near future. Hezbollah armed with chemical and biological weapons could lead to very interesting times, and if they are armed with Scud missiles you have to assume they have wmd's.
