Thousands of US diplomatic cables were leaked, and now relations with other countries that have taken years to grow and maintain are at risk. And that is just the lesser of the possible negative effects of the leaks
Although I am a firm believer in the First Amendment rights of everyone, I do believe that the safety and well-being of Americans is more important. The leak of these classified documents to the entire world is a show of weakness to the everyone around us.
I believe that Putin's criticism of America after one document from American defense secretary Robert Gates icily described Russia's current government was every bit justified. Although Secretary Gates' opinion is important and most likely true, it is not something that Russia, or for that matter, even Americans needed to know about.
The actions of this person who is supposed to not only an American soldier, but American soldier, are not excusable. He has undermined US-international relations that are going to be extremely hard to mend.
So I believe that Putin had every right to discuss his issues with the US on "Larry King Live". Those are things that he should have never heard through a leak on the internet. His country did not deserve to be publicly humiliated, no matter if it is true or not, in the way that it was.
