Atheism and foriegn policy

I found this article on huffington post about atheism and foreign policy.

http://www.huffingtonpost.com/robert-wright/why-the-new-atheists-are_b_230448.html

He talks about how new atheists are very hawkish in their ideas of foreign policy. He brings up an interesting point, that i would like to talk about. because new atheism believes religion is one of (if not the most) problems the world faces, they have essentially declared war on religion. So their world view is seen through the glasses that if one just eliminates religion the problems of the world would go away, or dramatically decline. Is this view constructive in dealing with foreign policy? Is this idea of eliminating religion a good and constructive goal to uphold?
