How can we justify this?

I saw a video shot by a Romanian cameraman on a mountain climbing expedition in Nepal recently. It shows Tibetan monks & nuns trying to cross the border into Nepal and some of them being gunned down by Chinese Red Army troops in cold blood. How appropriate that today is the 50th anniversary of the Chinese invasion of Tibet. This video is a classic example of how religious freedom and freedom in general in Tibet has been squashed by the Chinese government. And unfortunately, we Americans have been financing this sort of repressive action by buying goods made in China. Now, I realize that many times one has no choice to do so since it seems that EVERYTHING is Chinese made. Thanks to companies like Wal Mart and many others, our markets are flooded with these goods, so that they can increase their already huge profit margin. And are you aware that we owe the Chinese government billions of dollars in Fed Treasury notes? What happens when the Chinese government decides to cash these in? This country wouldn't have the resources to pay that. And then what happens? Your guess is as good as mine in this case. This may seem like it means nothing to you in your own life, and that is more than likely true, but in a country that talks a lot about personal freedoms, can we as a nation continue to justify and allow the actions shown on this video?
