"Although the Biden administration has successfully rallied U.S. allies and provided substantial military assistance to Ukraine’s valiant armed forces, it has failed to produce a satisfactory strategic narrative. By providing aid sufficient to produce a stalemate, but not enough to roll back Russian territorial gains, the Biden administration may be unintentionally seizing defeat from the jaws of victory.

With the necessary weapons and economic aid, Ukraine can defeat Russia. If it succeeds, our soldiers are less likely to have to risk their lives protecting U.S. treaty allies whom Russia also threatens."
