Bush's Shrinking Safety Zone

[headsplice]

Iraq is probably closest in that analogy. US boots deployed under false pretenses and thrown into combat conditions they're wildly unprepared for. Maybe.
Afghanistan is not AT ALL close. And the Israel/Lebanon thing? You might make the case that if the US had boots on the ground, it maybe would be sort of analogous to Korea, but Viet Nam? Pshaw.
And the fact is, Hezbollah is an Iranian creation. The were trained and funded by Iranians, and support and material are funneled through Syria. Actually, the most interesting argument that I've heard is that Iran uses Hezbollah as a counter to US interests in the region. If the US attacks Iran (and the wardrums are already rolling), Hezbollah launches a counter-attack against a US ally.
