Strikes me we've got far better tentacles into the relevant populated areas in Iraq now, rendering this sort of thing out of the question--But those who are there will know better if I'm just whistling Dixie.
I'd submit that our tentacles in Iraq are far less fearsome than the GVN and American forces in RVN - rather the enemy is far less capable, organized, and centrally directed than the NLF/NVA. Indeed, its major constituent blocs are engaged principally in fighting each other at the moment rather than engaging the U.S.
