It depends on how far back you want to go, some countries barely merit being on that list as they're barely a year old. Within the last 9 years, the following countries have either uphelp an overall better record, or have made more progress in improving Human rights, in regards to both internal and external Human Rights violations and based on their involvement with the United Nations: The Kingdom of Cambodia, Republic of Kosovo, Socialist Republic of Vietnam, Kingdom of Swaziland, State of Qatar, and the Republic of Tunisia. The Republic of Iraq and the Islamic Republic of Afghanistan cannot be compared alone as they're under both American and International control/influence, thus not fully independant nations as long as the war continues.
You can cross check for reference several of the latter countries with Amnesty International and the (American) State Department's 2005 Country Reports on Human Rights Practices
; I'm not dismissing that these countries are free of problems either, but rather that these ones have over the last 9 years maintained a relatively better record than the United States. Also, don't let yourself be fooled by the mediatization of each of these countries, nor by the United Nations' list of best and worst countries to live in, which focuses on completely different aspects.
But I also want to point out that although the State Department's report omits the United States itself, it lists a great deal on the majority of the world's countries and violations in regards to Human Rights. It should be clear enough that no country whatsoever fully abides Human Rights.
While I don't support torture I also think the deaths of 1000's of my countrymen and the destruction of the two WTC buildings is wrong too. (And the 100+ that were killed when a plane crashed into the Pentagon.)
You need to learn to distinguish between what your own government considers a 'terrorist organization' and a nation. The invasion of Afghanistan has led to a death toll of up to 1.3M, with up to 1.2M deaths in Iraq. Barely a tenth of these deaths are ever reported or documented. I neither agree with what happened in 2001, but I honestly believe that the government's war-frenzy politics that ensued caused more harm to its country and its reputation on an international level.
As for the racism, I'm not merely referring to African-Americans, but also Aboriginals, Mexicans, and people from the Middle East. If racism attains a level of torture and detainment without any rights (e.g. to a fair trial) still today, then the American government must be judged by the same rules as all other nations. If you truly advocate for Human Rights, you must be prepared to point out your own flaws, not just those of others. Canada is also no exception.
And I should have written toxic waste rather than nuclear waste, as I couldn't find any articles any more recent than the eighties. The Somalian one just mentions Western countries in general, and possibly some Asian countries may have been implicated as well. My bad on the terminology though. In regards to toxic waste, here's one
, and another
Also, writing a post is not the same thing as having a country entirely devoid of censorship; simply put, "Freedom of speech, is not a legal absolute" (Bidgoli, 2004). "Censorship in the United States doesn't involve overt, heavy-handed, formal rules of reporting or the killing of new stories by government censors. Instead, (...) it is a subtle system of information suppression in the name of corporate profit and self interest" (Perrucci & Wysong, 2007) And for a third book, I recommend "Sur la télévision", by Pierre Bourdieu, which tackles some of the brouhaha concerning censorship, media, corporations, and governments.
