Frankly, I am surprised this wasn’t done months ago. Ukraine must institute universal draft. All Citizens are to serve! Children as young as 14, boys and girls, men as old as 76, priests, nuns, politicals, even foreigners visiting should be drafted into national service. Like Mohamid II said when he attacked Constantinople, all must go to the fight, any still in camp would be killed—cooks, hookers, doctors, imans, all must fight—and he won the day. A nation in arms can not be defeated.
WWII Germany did this at the end in 1945, drafting young boys and old men and arming them for the defense of the Fatherland. It didn't stop the Russians or the Americans from marching straight to Berlin.
