sweet, looks like it is getting the results for countries with two spaces like

United States but not getting single countries like Thailand is in both .txt files but still outputs in the results?

Thanks

Code:
awk 'FNR==NR{sub(/[ \t]*$/,"");a[$0];next}
{sub(/[ \t]*$/,"")}
!($0 in a)' db.txt allcountries.txt

Try
Code:
$ grep -vf  db.txt allcountries.txt
United Arab Emirates
United Kingdom

If spaces lead to inconsistencies, trytr -d " " <file|grep -vf <(tr -d " " <file2)
