Some of you gents who seem a little uneasy about American dominance of the world should give a little thought to the following.
The Chinese actually got the idea from big billboards outside American military bases.
"Pardon our noise.. It is a sound of FREEDOM" on one side of the billboard and the American flag waving proudly on the other half of the sign.
Nothing bragging about these eye catching signs, they just stand there for all to ponder. Think about this.
