For my part, I find the jingoism sad. When "Support our troops" becomes a stand-in for "support this war", with the implication that if you don't support the current conflict, you're somehow being traitorous to the people at the sharp end, well, that I have a problem with. Sometimes, "Supporting our troops" should mean not sending them.
I forgot where I read it or heard it, but I became aware of an argument once that an all-volunteer military has one disadvantage over a conscripted military. When soldiers are all professionals, in that they chose that way of life, there may be a tendency for their political masters to think of them as their own private mercenaries. When draftees come home in body bags from places no one cares about, and for no obviously good reason, the electorate might get uppity. When mercenaries get killed or maimed, only a small number of people care. This is very cynical, but boy it's hard not to be cynical when it comes to people in power.
