Poland does not care about the peace in Eastern Ukraine, or in the East in general, nor about the well-being of the Ukrainians. The Polish politicians, thinking in the anti-Russian categories, perceive Ukraine as an important issue only if it harms Russia. Otherwise, if Ukraine stops harming Russia, the Polish politicians and publicists lose their interest in this country.
The Polish government is submissive not only to its main ally (or even a hegemon) – the United States but also to much smaller countries such as Israel. The evidence for this statement is the recent anti-Iranian conference in Warsaw, which was in reality organized by the USA and Israel. Polish independence is weakening, or it has already been completely liquidated.
A common pro-Kremlin narrative on the “lost sovereignty” - in the case of Poland, this country is often presented as a “puppet-state” of the United States. The statement that Poland is submissive to the will of the United States or other countries (Israel) is a conspiracy theory. Poland is a sovereign state, which shapes its own foreign and domestic policies.
The Middle East conference in Warsaw took place on February 13-14, 2019 - it was officially organized by Poland and the United States. This event united 43 official delegations (mainly, from the countries of the European Union, Middle East, Middle Asia and North Africa). The main official issues of this conference were terrorism and extremism, missile development and proliferation, maritime trade and security, and threats posed by proxy groups across the Middle East.
