Indubitably. From the article: Collisions are rare, but half of all near-misses today are caused by debris from just two incidents. In 2007, China destroyed one of its own satellites with a ballistic missile. In 2009 an American commercial communications satellite collided with a defunct Russian weather satellite. There are only a handful of nations with the launch capabilities, but if any one of them wanted to ruin the party for everyone, they could probably accomplish it by hitting a few satellites with a few missiles. I don't imagine it would take very many destroyed satellites to create a serious debris hazard.
