Newspaper theme — can I have a drop-down that acts like a filter?

Hi I am trying to build my site with country filters, and I am wondering if it is possible.

Here is a brief description of what I would like to accomplish:

1) I am building an international news site for my industry — with articles about the industry in several countries.
2) I am creating a few sections for my stories by type: Business, News, Opinion etc. These will be my main menu items, each will have its own menu page and I may have some sub-menus
3) I am going to have stories in each section from different countries. Ex. UK, US, Canada, etc. I was planning to use tags for this, and tag the stories with the country they are from.

(these first 3 requirements are very basic and easily accommodated by the theme)

4) (Here is the main requirement) — I would like to have a dropdown menu item with a list of countries, and when a country is selected, then in all sections the user would only see the articles specific to that country.

For example: if the user picks “USA”, he’ll only see articles in each section that are tagged USA, not other countries. If he switches to UK then he’ll only see the articles from the UK in each of those sections. When he/she wants to go back to seeing all, he just goes back to the dropdown and selects “all” and then can see all stories again.

Is this possible? If so, how? Thanks so much for your help.
