Mateusz Morawiecki made the remark at a briefing in Warsaw on Thursday night, Polish state news agency PAP reported.
Morawiecki said: “Poland must keep alive the discussion about Ukraine, about freedom, about how important it is ... to fight against Russia.”
He added: “This is because the West is increasingly tired of what is happening there.”
Morawiecki also said that “the Western public must be aware that here and now, the future of Europe, if not the world, is being decided.”
The prime minister reiterated Poland’s call for Berlin to allow the transfer of German-made Leopard 2 tanks to help Ukraine fend off the Russian invasion.
He told reporters: “German tanks, Finnish tanks, Danish tanks, French tanks must be sent to Ukraine. Western Europe must now allocate a sizable amount of modern tanks to Ukraine so that Ukrainians can defend themselves.”
Morawiecki warned: “Unfortunately, the cruel war is reaping an increasingly bloody harvest. The situation in Ukraine is increasingly dire.”
He urged Germany “to realise at last that we must help with all our strength to save the freedom, democracy and sovereignty of this wonderful European country.”
Friday is day 331 of Russia’s war against Ukraine.
