Bring em' on !

hello,
That phrase has been said by Mr.Bush once. What does it mean and having been said by a statman, what does it signify? Thank you all.

It signifies that President Bush was trying to sound like a "tough guy." I don't think that is a very statesman-like phrase. Any comments from my fellow Americans?

It's something I might envision Harry Truman as saying, under different circumstances--when U.S. troops would not be immediately endangered by the challenge, for instance. The difference, of course, is that Truman fought in France, and had cojones, instead of going AWOL from a joke National Guard program.
