filter homepage content based on term id
Okay, now i understand your problem!

When a user clicks on a link in the "countries" page, he will see the standard taxonomy term "view". But i guess you want him to see your normal "homepage" BUT with filtered content.

You have two options:


Alter the taxonomy term page.
Use contextual filter on the "homepage" and change the links on the "countries" page according to use the filter.


In my opinion you should clearly prefer option two. Also have a look at the view "Glossary", which should be included, but not activated out of the box, this should help you a lot in configuration!
