Of course that means that Iran and Syria have to be dealt with - and that is the 'wild card' - but they have to be dealt with - firmly - as diplomacy seems to escape both of these state-sponsors of terrorism.
While I agree completely that Hizballah, Iran, and Syria all need to be dealt with how do we convince other nations to help while we are strung so thin? Israeli action is not generating support for dealing with the root problem - which is Hizballah's continued existence and ability to strike Israel from Lebanon.

No one, and especially the U.S., can truly fault Israel for their actions which have been taken to protect not only their military but their civilan population. It seems that not enough attention is paid to the fact that there is a U.N. Resolution that called for Lebanon to disarm/control Hizballah - something they have not done. Would the U.S. stand by and allow any organization to launch rocket/mortar attacks from Mexico or Canada?

Viewed in terms of strategy, it is ultimately in Israel's best interest to encourage and facilitate both a healthy Palestinian and a healthy Lebanese government
Finally I again agree it is in Israel's strategic interest to see a stable and healthy Lebanon and Palestine, but how long can they be expected to tolerate attacks from the territory of a soverign nation before they act?
