If you read the article, the answer is zero.
Let's see, the U.S. spent billions to not determine the Soviet Union was going out of business.
Since then we've spent how much keeping an eye on russia? Trying to persuade them to act like responsible internationalists? Thinking we've a "partner in peace".
Oh, but we've not spent bucks to determint russia isn't a friend?
Maybe not for this article there pal.
