Ukraine is releasing to Russia mainly Ukrainian citizens from East Ukraine, which means that Kiyv should not be offended by those who call events in Ukraine civil war. De facto this is the case, we [Russia] are receiving participants of the civil war. The prisoner swap legally confirms that.
Tensions since the end of the USSR come from Moscow. It is the United States that are literally colonising Poland.
Everyone knows geography. There is natural gas that costs less. Yet the Poles – for some reason – buy the gas ten times farther than where it is produced in an abominably anti-ecological way in the United States and which is much more expensive. They are literally forced to buy American equipment. There is also an over-presence of US military forces. The Poles, unfortunately for them, were under Soviet influence and now they are under the influence of the United States.
"Colonisation” refers to methods of absorbing and assimilating foreign people into the culture of the imperial country, populating them, imposing unfair trade, banning their local culture and language. The fact of buying gas in the US cannot be considered as colonisation. Poland, as a sovereign country, makes its own decisions as to where to buy gas.
As for NATO (not US) troops, around 5,000 troops already rotate in and out of Poland. This is part of a 2016 NATO agreement. No intervention of these NATO forces in Polish internal political process, banning of Polish language or settlement of Americans or any other options except defensive are considered. Thus, Poland cannot be called a not independent state or a colony.
