Jeff Agoos? Agoos grew up in Texas. Tab Ramos more or less grew up in New Jersey. Regis was brought in at the last minute and immediately sowed resentment as a result. Those are some bizarre examples you're using to make your point. Tom Dooley and Ernie Stewart are better examples, but they were brought in at a time when the average U.S.-developed player was awful and the program was in its infancy (and there was no domestic league to develop players).
So what constitutes someone being an American? Do they have to live here for a fixed time? Sorry about Agoos, that was an awful example, but besides him all of those players were born outside the U.S. to either one or less American parent. Yeah, players showed resentment towards Regis in 1998 because he was foreign and that he was 'taking their job' (you could also make the same argument on him that you did on Stewart/Dooley) but don't remember any resentment towards him in 2002. To your point on Stewart/Dooley, even with the improvement of the U.S. domestic player, our best player is still a 'foreign guy'. What does that say?
Jermaine Jones, Mix Diskerud and Terrence Boyd... two of those guys can barely speak English. Doesn't mean they don't care about the team, but how in hell are they three of the most "American" guys on the team? Two of them had barely any contact whatsoever with the one parent who gave them their U.S. citizenship.
Who cares if they can't speak perfect English, is that some requirement to be a member of the MNT or something? Have you ever heard Terrence Boyd talk about the United States? Dude is more publicly proud to be an American than pretty much anyone else in the pool. Not to mention, suiting up for the U.S. made Jones become closer to his father than he ever was as a kid.
I'm far from a xenophobe and I'm far from a flag-waving nationalist. I've been living abroad so long I consider myself to be a human being rather than an American, but to act like all these guys who previously had barely any connection with the U.S. apart from a piece of paper with their name on it are some kind of lion-hearted, red-blooded Americans is silly. They're guys Klinsmann brought in from overseas because because of serendipitous bloodlines, and just because Abby Wambach is the only person who dares to say it in public doesn't mean she's the only American player thinking it. Players should be brought in solely according to what they've accomplished and are capable of, and that automatically rules out a bunch of the players JK has brought in at the expense of numerous domestically based players.
Again, what makes someone a 'red-blooded, lion-hearted American'? Okay, I'll bite. Which players, outside of Julian Green, that Klinsmann has called up don't deserve to be? Chandler? He's been pretty bad for the U.S., but the dude's a starter in the Bundesliga (a very good one at times). Williams? Again, it's not like he's riding the bench somewhere. Brooks? Nope. Alvarado? You'd probably have a point there, but he's still only 23, so there's room to grow for him. Orozco? I'm not his biggest fan, but he's actually been fairly decent for us. Jordan Morris? Oh wait, he's a white guy from Seattle. He doesn't count.
You're... you're making me defend Klinsmann... I don't like this.
This has little to do with "expanding the talent pool." It's one thing to expand the pool. It's quite another thing to make boneheaded roster decisions based on where players grew up, and Klinsmann appears to have done that on numerous occasions - the most glaring example being when he replaced our best player ever with Julian freaking Green.
Donovan sucked for the first part of 2014. His play/form didn't earn a roster spot, end of story. Why assume that Green knocked Donovan off the team anyways? It could easily have been Brad Davis.
