NATO creates military tensions in the European Union and is trying to provoke Russia. The new US-Polish agreements are in conflict with the Founding Act of Russia-NATO, signed in 1997. According to this document, the North Atlantic Alliance should refuse to deploy significant combat forces on the territory of the member states.
On June 12th 2019, the United States and Poland signed a Joint Declaration on Defence Cooperation. The main agreements are to increase the presence of the US military and create special bases for them in Poland. Currently, about 4500 US troops are based on a rotational basis in Poland. It is assumed that, in the near future, the contingent will increase by another 1000 troops. Earlier, the USA said that they were not going to send additional troops to Europe, but an increase in the contingent in Poland could occur due to the relocation of the US military from Germany.
Thus, no NATO treaties with Russia will be violated, as the total number of military personnel in the European Union will not change, only a redeployment of troops will take place.
