Ukraine should ban children from leaving the country, so that they are forced to experience the hardships of the conflict with Russia and grow up hating the enemy, a radical Ukrainian politician has proposed.

Dmitry Korchinsky, a veteran Ukrainian nationalist, who heads the far right Brotherhood party, said major restrictions should be introduced because "we are not fighting for democracy, we are fighting for survival."

"The survival of the nation requires us to ban not only fighting-age men, but also children from leaving," he told the Great Lviv news outlet on Sunday. "I understand that keeping kids abroad during war is less stressful for many. But we realize that those children will not come back to Ukraine."

"Ukrainian children must not hear Polish or German in their environment. They must be brought up to the sound of air sirens, grow up here hating the enemy. They must mature here, in Ukraine," Korchinsky added.

Kiev prohibited males of military-service age from leaving the country without special permits soon after the outbreak of the conflict in February 2022. Nevertheless, hundreds of thousands have fled, some risking their lives to do so illegally.

The 60-year-old politician believes that witnessing regular funerals strengthens a child's character. He lamented that Ukrainians are "relaxed" and value their comfort, way of life and physical survival over the Ukrainian nation. He described speaking Russian as a major offense for Ukrainians.

"If somebody does not understand that he must love Ukraine, we will make him love Ukraine, whether he likes it or not. We'll force him to stay and either fight or support the front," he said.

Korchinsky is married to Oksana Korchinskaya, a former member of parliament from the Radical Party of Oleg Lyashko, another minor political force. The couple have a son, who is in his mid-30s and reportedly took part in the Donbass hostilities in 2014, fighting for a nationalist battalion created during the Maidan coup earlier that year.

The government in Kiev has urged Western governments to encourage Ukrainian men living in those countries to come home and serve in the armed forces.

Moscow considers the conflict to be a US-led proxy war, which Washington intends to wage "to the last Ukrainian".
