To confront Kremlin aggression, Ukrainian President Volodymyr Zelenskyy declared Tuesday a "day of unity."
To achieve the same objective, President Joe Biden has galvanized a new era of unity among NATO allies and partners. While the solidarity may not prevent a Russian invasion, it has so far clearly communicated a consistent message to Russian President Vladimir Putin about the military, diplomatic and economic cost of any incursion.
And the NATO support has reassured Zelenskyy that Ukraine, like all sovereign nations, has a right to determine its own military and diplomatic direction.
