McCain: "We Have Just Found Out"

I find this McCain quote interesting:

"It's very clear that the overriding issue is the economy. Americans are hurting very badly...but I also think that national security is an underlying issue because we have just found out in the last few days that we live in a very dangerous world and there are situations which can arise which were not readily foreseen, certainly not by average citizens...that require experience, knowledge, and judgment." [My emphasis]

He "just found out in the last few days that we live in a very dangerous world"? Where's he been all his life?
