{IF {Mergefield Country_Abbrev} "US" "{Mergefield Country}"}
will do that. Note that the field boundaries {} are inserted with CTRL+F9
and that fieldnames should not have spaces.
however if the fieldname does have a space, it might work with
{IF {Mergefield "Country Abbrev"} "US" "{Mergefield Country}"}

I have a mail merge label document. I want to conditionally print
one field - ie, if the Country Abbrev field is NOT US, then
print the Country field otherwise leave blank.
