As Russia's invasion of Ukraine drags on, and western aid for the underdogs grows, more people ask how far we are willing to go to defend another country and how much we're willing to risk. It's difficult to find somebody who doesn't sympathize with the Ukrainians, but that doesn't mean we shouldn't worry about the price of supporting a war against an autocratic regime that seems unconstrained by human decency and that commands not just tanks and troops, but nuclear weapons.
"Anyone concerned about the cost of supporting a Ukrainian victory should consider the much larger costs should Ukraine lose," Senate Republican leader Mitch McConnell (R–Ky.) commented last week after a bipartisan majority approved $40 billion in additional assistance to Ukraine.
