Will international investments make your retirement nest egg last longer?
The answer to that question comes from the same three Trinity University professors – Philip L. Cooley, Carl M. Hubbard and Daniel T. Walz – who did one of the original studies of withdrawal rates and portfolio survival. Writing in the May issue of the AAII Journal, the monthly publication of the American Association of Individual Investors, the researchers compare survival rates for portfolios with, and without, international investments. They compare, for example, survival rates of a portfolio that is 50 percent U.S. stocks and 50 percent bonds with a portfolio that is 25 percent U.S. stocks, 25 percent international stocks and 50 percent bonds. They do this for equity allocations ranging from 100 percent down to 25 percent.
Their conclusion?
International diversification probably isn't worth the trouble.

It's nice to get confirmation on that, but Buffett and Bogle have been saying the same thing for quite a while.
