I would like to know about their Politics, please.

I didn't know that, anything else on politics?
The Iceland Defense Forces was a military command of the United States Armed Forces from 1951 to 2006.
Oh ok! How about their History?
On May 5th 1951 a defense agreement was signed with the United states and on September, 30th 2006 the US withdrew the last of its forces.
Why did the US withdrawl their forces?
