Hezbollah's international capability

The Terror wonk, here, makes some interesting comments about recent Hezbollah threats and current capabilities.  Following the comment on the New York CT post below about Hezbollah threats, it makes the point that Hezbollah's operations internationally seem to have been limited or contained.  It links this in part to careful monitoring of Iranian embassies activity which it cites as being an important cog in Hezbollah's international capability.

As an aside, the blog referenced makes an assumption that Hezbollah's last main international terrorist attack was the 1996 attack on Khobar Towers in Saudi Arabia. Whilst indeed that is what the Saudi authorities assert, I remain unconvinced.  There is little evidence, and in my opinion the attack may just as easily be the responsibility of sunni militants in Saudi , who after all have mounted dozens of attacks in the meantime.
