Ukrainian President Petro Poroshenko is confident that Ukraine, along with its allies, will defeat the Russian aggressor and establish peace.

"Eternal memory of the enormous victims of the Second World War, of thousands of ruined cities and tens of thousands of burnt villages once again warns the world against the danger of repeating such a catastrophe," he said during the ceremony of taking military oath by the new replenishment of the 101st separate guard brigade of the General Staff of the Ukrainian Armed Forces in Kyiv on Wednesday.

The president noted that it had already been proved "by irrefutable facts that Stalin's Russia and Nazi Germany have been allies for almost two years (1939-1941). The war that the USSR unfolded against Finland, annexation and occupation of the Union of Latvia, Lithuania and Estonia is the same example of aggressive actions that the Nazi regime was carrying out in Europe even before sending weapons against the former eastern ally. The peoples of the Soviet Union, including us, Ukrainians, paid a very high and terrible price for this," the president said.

According to the president, today "Putin's Russia has once again embarked on a path of gross disregard for the norms of international law, the destruction of the world order, the non-recognition of borders, the denial of the existence of entire nations, and aggression against neighboring states."

"I am convinced that we will win together, we will overcome the aggressor and ensure peace. Peace is what Ukraine needs. And peace on Ukrainian soil will be ensured," Poroshenko said.

He congratulated the citizens of Ukraine on Victory Day over Nazism in the Second World War.
