Thanks for the links. I had understood there was a link between Hezbollah and Iran; what was less clear was how they threatened the American people. In reading the CFR report and briefly looking over the Global Security article, I'm not convinced that our security is threatened by them. John Quincy Adams' comment still applies: "We do not go abroad, in search of monsters to destroy."
Afghanistan was far away..They had no weapons to threaten our security we thought....not here.
