Strangely enough, me too. My father, his father, his father - going all the way back to before the turn of the last century. Plus, my only son is in uniform today along with one of my daughters. It is sad that we've had difficulties meeting the minimal recruitment goals with such a large country, but it is what it is. Kids today, and people in general don't feel like they have any obligation to serve. I would bet that a very significant percentage of kids in the military today come from families where either their parents or siblings have served, it seems to be a common thread.
With respect to Beck's advice to his nephew, it was poor. Barry could choke on his arugula tomorrow and (Lord forbid) Biden could be POTUS. People have a bad habit of thinking "now is forever". It isn't. Obama, and his leftist minions, want a demoralized and shrinking military, of that, I have no doubt. Conservatives shouldn't be in the position of encouraging it.
I used to think that almost all men served, I thought the difference in military service was pulling a hitch or making it a career, I did not know that the difference was serving or not serving until I was into adulthood.
I still work on every good young man that I can to join up, I recently had a neighbor kid tell me that he had enlisted because of me, unfortunately he came up with a medical problem that lost him his enlistment, but he will always be able to say that he put himself in front of the recruiter (and meant it).
