Useful to hold foreign bond fund?

[soupcxan]

With the dollars continued decline, is it worthwhile to hold 5% of a foreign bond fund to help balance things out? Can the fund help add some low/negative correllation with US equities? I imagine it would be more volatile than a US bond fund but I am not so concerned with that...just looking for new asset classes that don't move in lockstep with US stocks/bonds. I really don't know much about how a foreign bond fund works, did a search but didn't find much info. Would appreciate some comments.
