The inauguration of US President-elect Barack Obama on 20 January 2009 will be accompanied by widespread expectation of change. The world will be watching and hoping for positive outcomes on many different issues. Ahead of his inauguration, Amnesty International’s new film First 100 days is asking the President-elect to take concrete steps to demonstrate his commitment to international human rights standards, including in the context of countering terrorism. Since the attacks on the USA on 11 September 2001, the US authorities have authorised and justified human rights violations in the name of national security: illegal transfers and detentions; enforced disappearance; torture and other cruel, inhuman and degrading treatment. The new administration and Congress must break with the past. President-elect Obama has already said that he will close Guantánamo and end torture. We’re not asking the impossible. We have a checklist for President Obama’s first 100 days in office. His first steps should be to:announce a plan and date to close Guantánamo ban torture and other ill-treatment, as defined under international law ensure an independent commission of enquiry in US ‘war on terror’ abuses is set up These things are possible and you can help.
