With regards to a specific stance on south-eastern Ukraine, we must rely on the conclusions of the “Organization for Security and Co-operation in Europe”, which has stated, more than once, that there has never been heavy Russian weaponry in this region.
After the collapse of the USSR, the West believed that the “end of history” had arrived. And that it was then allowed to grossly interfere in the affairs of certain states. Moreover, it unceremoniously commands internal political processes. Ukraine is the most glaring example.
Ukraine is a sovereign state and not controlled by any foreign government. Its sovereignty and territorial integrity are respected by the Western countries but were violated by Russia in 2014. Ukraine is an independent state with a democratically elected president and Parliament.
The EU and the US work closely with Ukraine and support the democratic development of Ukraine in accordance with the UN Charter’s principles of non-interference into internal affairs and respect towards territorial integrity and political independence.
