The United States of America, the Russian Federation, and the United Kingdom of Great Britain and Northern Ireland, reaffirm their commitment to Ukraine, in accordance with the principles of the CSCE [Commission on Security and Cooperation in Europe] Final Act, to respect the Independence and Sovereignty and the existing borders of Ukraine.
The US couping Ukraine's government to install a neo-Nazi regime back in 2014 (not to mention Orange color revolution in 2004) isn't a violation of Ukraine's sovereignty, but Russia responding to that is? Make that make sense.
