The US dollar as world reserve currency is the source of American imperialism. The five countries that comprise the BRICS have half of the world's population. They can conduct their economic affairs without the dollar.
The world needs to understand that the neoconservative US government is the Third Reich on steroids. It is a malevolent force with no sense of justice or respect for truth, law, or human life. Just ask the residents of Iraq, Afghanistan, Libya, Syria, Palestine, Pakistan, Yemen, Somalia, Lebanon, Honduras, Venezuela, Cuba, Iran. Even the deluded western Ukrainians will soon catch on.
Obama himself declared that the US is "the exceptional nation." This is the neoconservatives version of Hitler's declaration that the German nation was exceptional and, therefore, above all others. The only difference between Washington and National Socialist Germany is that Washington has a far more powerful police state and nuclear weapons.
The hubris and arrogance that arises from Washington's belief that it is the government of the "indispensable and exceptional nation" means Washington has no respect for any other country, nor for law whether its own or international. Washington can invade countries without cause, a war crime. Washington can kidnap and torture people, a crime under US and International law. Washington can ignore the self-determination of peoples, such as Crimeans. Who are mere Crimeans to vote on their own future without Washington's consent, without Washington determining the outcome? Washington declares the Crimean people's self-determination "illegitimate and illegal," and refuses to recognize self-determination, while pretending to be the home of "freedom and democracy."
No government in human history can come close to the hypocrisy and malevolence of Washington. Armed with nuclear weapons and a military doctrine of pre-emptive nuclear first strike, Washington alone stands as the threat to life on earth.
