Sikorski was speaking after talks in Paris with his French counterpart Stéphane Séjourné and German Foreign Minister Annalena Baerbock.
The talks focused on military and industrial cooperation between the three countries, European defence initiatives, and continued support for Ukraine as it struggles to fight off Russia's invasion, according to the Polish foreign ministry.
"We have a war in Europe again, with a dictator who has arrogated to himself the authority to determine the status of nations and the right to change borders in Europe by force," Sikorski said at a joint news conference with Séjourné and Baerbock.
He added that "Putin is trying to enslave and conquer Ukraine with lies and demagogy, and to destroy the European Union and NATO," Polish state news agency PAP reported.
“We must not allow Putin to win this war," Sikorski stated emphatically.
"We must fulfill our obligations toward Ukraine," he added, listing the supply of ammunition and financial support, among other priorities.
Meanwhile, France's Séjourné told reporters that Europe must urgently prepare for the possibility that the United States might not protect NATO allies who are not spending enough on defence, the Reuters news agency reported.
"Everyone has heard the comments of the Republican candidate in the US elections in recent days," the French foreign minister said, referring to remarks by former US President Donald Trump, who said at an election rally on Saturday that Russia should be able to do “whatever the hell they want” to NATO countries that do not meet their defence spending targets.
"I will not cease persuading all the leaders of the pertinence of our alliance, which works for the benefit of all, including the United States," Séjourné added, as quoted by Reuters. "Every minute counts to prepare Europeans to absorb the shock of a scenario outlined by Donald Trump, and we will work together to analyse the context, notably of the US elections."
Poland, France and Germany together form what is known as the Weimar Triangle. The group was set up by the three countries in the early 1990s to help overcome divisions in Europe by bringing Poland into the European Union and NATO.
Russia invaded Ukraine on February 24, 2022, starting the largest military conflict in Europe since World War II.
Monday is day 719 of Russia’s war on Ukraine.
