Russia was dedicated to haShem. Asking Russia to give up the Crimea is like asking Israel to give up Yerushalayim. It is asking too much. President Trump needs to understand that and he needs to understand war with Russia is too great a price to pay for the Crimea. Also, President Reagan got Russia to end the Cold War and take down the Berlin Wall in exchange for the West's promise NEVER to put NATO forces and missile defense systems and missiles in nations bordering Russia. That agreement was broken by subsequent US Presidents and the consequence is World War III unless the West backs off. There are even US tanks on the border of Russia!
