By word and deed, the biggest nuclear powers have shown that weapons of mass destruction are on their way to becoming things of the past. To reach their Prague agreement, President Obama and Medvedev had to neutralize influential opponents of disarmament in their respective countries. This spring alone, the United States and Russia signed a strategic arms reduction treaty and world leaders have taken steps to block nuclear programs in Iran - including a sanctions agreement announced last Tuesday - and North Korea. Indeed, those who dream of global nuclear disarmament have reason to feel optimistic. The rise of corruption leads me to an inescapable conclusion: While world leaders are proving capable of addressing nuclear terrorism, one of the most difficult issues facing the international community, they still must do more to address such evils as corruption, which holds entire peoples and countries hostage. But Russian President Dmitry Medvedev, who has taken the initiative to fight corruption in law enforcement in our country, should know how his efforts are being undercut by his own officials. The courts' actions have made it clear that I am going to be imprisoned no matter what. I did not do this to raise awareness of how my own legal case has been unfairly handled. Last week I held my fourth hunger strike since being jailed on trumped-up charges in 2003.
