I highly doubt any "national will" would be spurred by any ARNG/Reserve call-up. Either the cause itself is enough, or it isn't. Then there are the commies who just aren't happy regardless of what our troops are doing, but who cares what they think?
Remember in the 1st Gulf War how most causalties came from one unit, a PA NG unit.
Part of the problem from Vietnam stemmed from no single community really made a sacrifice, but during the Gulf War (and this one) whole comminities were affected by call up of the Reserves. The current Military design is to cause upheavel. communities thoughout the U.S. were/are affected.
