Many don't know how to remove the internationalization options of google.
Here is a answer:

As you have discovered, Google normally redirects
users in certain countries from www.google.com to one of our local
destination sites (for example, www.google.fr for Google France). We use
the Internet address assigned to your computer, which is frequently the
Internet address of your Internet service provider (ISP), to determine
which Google site corresponds to your geographic location. We also offer
you the option of avoiding this redirect and using www.google.com instead.

If you've been redirected incorrectly or aren't being taken to the Google
site you prefer, follow the instructions below to direct your browser back
to www.google.com. As long as you have cookies enabled in your browser,
you'll only have to do this once; after that, your browser will connect
directly to www.google.com each time you visit Google. For more
information on cookies, go to http://www.google.com/cookies.html
and http://www.google.com/privacy.html.

On the bottom right-hand side of the page is a link that says
"Google.com." When you click on this link, you'll be taken to
www.google.com on all future visits.

It's very important to note that your browser will only "remember" that
you are opting out of Internet address detection if you have cookies
enabled. If cookies are disabled, you'll experience the same redirect each
time you visit Google. You can solve this either by enabling cookies in
your browser or by setting a new bookmark for http://www.google.com/webhp.
In the latter case, you'll be taken to http://www.google.com/webhp (this
is exactly the same as www.google.com) each time you select the bookmark.
