Canada? We've never gone to war with Canada. Doesn't that make us peaceful, as it makes them?
Mexico, we have been attacked by before. And we've attacked as well. Does that make Mexico a war-mongering state, as your comment seems to insinuate that US is?
How many countries, cultures, villages, bloodlines did Russia annex into its mass in its history? Was that done peacefully? Was it "forced" on them, as the comment seems to communicate? Or is it possible that the un-peaceful neighbors of Russia have simply been around long enough to see what occasionally happens to "neighbors" for their too-close proximity? (Hey, where did that little country go? I could have sworn there was something to the left of Russia, just right here... nope? Oh well, my imagination)What happened to Voltaire's beloved "Sparta in the morning, Athens in the evening?"
And if you look into China's history, you'll find that they were not averse to War-mongering. In fact, Sun Tsu made some clear comments toward that end in his opus. Once again the question comes to mind.. what happened to all those little individual, fierce, proud states that used to dot the land of what has now become one massive country, called China?
What is the meaning behind the words "Free Tibet"?
I'm not going to disagree, that America has a tendency not to back down from a fight. But we're certainly not the only world power with that tendency. Though, it looks like we're going to wear that mantle if people want us to, and not much can be done to change it.
