Until Russia withdraws from Ukraine — both Donbas and Crimea — and recognizes that Ukraine is an independent, sovereign nation, other nations cannot be secure. Until Russia recommits to a rules-based international order, Western nations are in jeopardy. Ukraine is the front line.
In an even broader sense, Russia’s attack on Ukraine and the West is an attack on democracy. The question of how nations govern themselves — democracy versus autocracy — is being fought out among and within nations. Russia, China, Iran, Egypt, Turkey, the Philippines, North Korea, Venezuela, Cuba, Syria — all are autocracies, all are unfree. In the contest between democracies and autocracies, the contest between freedom and unfreedom, Ukraine is the front line.
