honestly, I've always had my international allocation anywhere from 10 to 20 percent in the last 8-9 years and they've been underperforming in comparison to the domestics.  It could be just that the selection of the international funds in my 401k is bad. 
  
 That said, I also have a personal bias and don't trust foreign accountings as much as domestics.  that and with everything currently going on overseas, I think it will get worse before getting better.

Yeah, I wish I had never put any international. I've been invested for the last 10 years in a fidelity 500 and international fund. International has really sucked but I keep thinking that has to change in the next 10-20 years. But I have the urge to switch to US every day I look at it.
