The British prime minister, the leader of the European Commission, and the presidents of Poland, Estonia, Latvia, and Lithuania have all visited Kyiv in recent days. They did so to let Ukrainians know that the West sympathizes with their sacrifices and suffering and to assure them of the West’s continued military and economic support. They wanted to show that freedom matters to them. President Joe Biden, however, has not yet been to the Ukrainian capital. His absence has not gone unnoticed around the world.

While there are legitimate security concerns over any possible presidential visit to Ukraine, they do not justify Biden’s avoidance of such a trip. The leader of the free world must be a witness to the most important battle for the future of the free world.
