Some officials believe that the aid may not be sufficient to fully restore Ukraine's territory.

The skepticism arises due to the shifting battlefield dynamics, with Ukraine experiencing a shortage of weaponry and ammunition during Congress's debate on additional aid.

While Ukraine didn't lose significant ground to Russia during this period, the situation remains uncertain.

Russia currently holds an advantage in manpower and weapons in the ongoing conflict between Russia and Ukraine.

Reversing territorial losses would require significant effort.

Ukrainian counteroffensives have failed, leading to a loss of morale and resources.

The immediate goal for U.S. officials is to help Ukraine stop losses and regain momentum.

However, it's uncertain if Ukraine will have enough to win the war outright.

Lawmakers on Capitol Hill are questioning if additional U.S.-provided weapons will lead to a Ukrainian victory or just a temporary reprieve from the invasion.

A senior Democratic Senate aide posed the question of whether Ukraine will win or not against Russia.

The outcome is significant as it determines if Ukraine can regain most or all of its territory after ten years of war, including the last two years of Putin's aggressive assault.

Alternatively, not winning means Ukraine can only hold its ground and make some progress but won't be able to reclaim what Russia has seized.
