Congress is about to provide Ukraine with another $12.3 billion in aid. That will take the total Ukraine-related U.S. aid to $67 billion since February. This massive U.S. commitment reflects a bipartisan priority that Russia not succeed in its effort to destroy a sovereign European democracy. China is watching what is happening in Ukraine very closely, assessing how the West might respond to its own invasion of Taiwan. The outcome of the war in Ukraine, then, is a key test of the post-1945 U.S.-led democratic international order.
