DailyTech's International Space Updates for January 2007
Some experts seem to agree that it is only a matter of time before an
asteroid or meteor strikes Earth in the future
. While millions of them are aimlessly floating around in space, 200,000 to 400,000 of them come within range Earth, according to reports. That is why NASA astronaut Edward Lu wants NASA to deploy a spacecraft which would be able to divert asteroids so they will not run into the planet. In theory, the craft's gravitational pull would change the asteroid's orbit. UK researchers are planning on using a
superior telescope located in Hawaii to help locate Earth-threatening asteroids
successfully recovered the Space capsule Recovery Experiment (SRE-1)
, a capsule that has been orbiting around the Earth at an altitude of 637km. The SRE-1 floated in space for 11 days before splashing into the Bay of Bengal earlier in the week. The Indian space agency used the SRE-1 to test its ability to accurately track and recover a space capsule landing back on Earth. The head of the team that created the capsule said that “the mission is a great success.”
Chinese space officials still continue to claim that its anti-satellite test is not a hostile act. The Chinese government confirmed that on Jan. 11 it launched a missile aimed at destroying an aging weather satellite, and the test has the United States and Japan worried. While the Chinese previously discussed its plans with U.S. Officials, both the Japanese and U.S. Governments want clarification on the future intentions of the Chinese. With some form of a space war on the minds of many government officials, this recent incident only has more people worried.

> "That includes spying satellites. Or any satellite that can take pictures, might even be agricultural."
If you read that statement as meaning the US would be randomly shooting down foreign spy satellites, you misinterpreted it, that's all.
And, as others have pointed out, the main objection to China's demolition of a satellite wasn't the capability itself, but the vast cloud of debris it created. Is China going to pay for any satellites it disables? I don't think so.

That statement does not mean US will shoot foreign satellites in a random way. But if a conflict does occur with a smaller nation, US government will find various excuses to shooting down communication satellites (saying they are used for military purposes or something else). It won't be a problem considering original justification for war in Iraq were WMD and majority of USA population believed it. It also means USA does not want any treaties putting limits on space warfare.
In the bigger frame, the worrying thing for the USA were not the debris, but the fact of China getting more and more advanced. Worrying is the proposition that in a possible conflict China might be able to shoot the US reconnaissance satellites out of the sky.

10-20 years from now, when the terrorist threat (irregardless of whether you think it is real or imagined) has been eliminated the next population motivating threat to be addressed will be asteroids. There is always a "grave threat" posed to the free peoples of the world. It sounds funny now, but mark my words, the next "threat" will be asteroids.
