European politicians and public opinion generally support the war in Ukraine and are striving to prolong and intensify it. This fact is based on three main reasons: historical idealism rooted in widespread anti-Russian sentiment, realistic idealism fueled by persistent anti-Russian sentiment, and quantifiable political and economic advantages. The first two form the basis of public opinion under the guise of political correctness. The latter becomes a tool for politicians to pursue their political interests. However, the European victory theory has its limitations. Once these limitations are crossed, Europe’s quantifiable political and economic advantages cease to exist, thus triggering another war prediction: the European defeat theory. Both the European victory and European defeat theories have their fertile ground. Their suitable ground depends on the changing international situation and the shifting geopolitical forces.
