I agree with Romney's assessment. However, The New York Times editorial today more or less agrees with you. Here is an excerpt from the editorial:
But as the war continues, Mr. Biden should also make clear to President Volodymyr Zelensky and his people that there is a limit to how far the United States and NATO will go to confront Russia, and limits to the arms, money and political support they can muster. It is imperative that the Ukrainian government’s decisions be based on a realistic assessment of its means and how much more destruction Ukraine can sustain.

Confronting this reality may be painful, but it is not appeasement. This is what governments are duty bound to do, not chase after an illusory “win.” Russia will be feeling the pain of isolation and debilitating economic sanctions for years to come, and Mr. Putin will go down in history as a butcher. The challenge now is to shake off the euphoria, stop the taunting and focus on defining and completing the mission. America’s support for Ukraine is a test of its place in the world in the 21st century, and Mr. Biden has an opportunity and an obligation to help define what that will be.
