"Here’s the pessimistic scenario: the Ukrainians are given missiles, they train their troops, they no doubt continue their offensive, and they try to counterattack. It’s possible that this counteroffensive is successful in some places and they restore the borders to where they were in 2014 — that could easily happen. They’ll attack Crimea, they’ll try to blow up the Crimean Bridge, they’ll cut off our supply routes. So we need to be ready for a difficult war."
