President Donald Trump has declared that Ukraine has the potential to reclaim all of its territory seized by Russia if it receives steadfast backing from NATO and European partners.

The statement, delivered on September 23, 2025, reflects a significant shift from his earlier suggestion that Kyiv might need to consider compromises on territory.

Trump made the remarks after meeting Ukrainian President Volodymyr Zelenskyy at the United Nations General Assembly.

He described Russia’s war effort as faltering under economic strain and urged European nations to intensify sanctions while reducing reliance on Russian energy.

He also stressed the need for NATO to enforce airspace protections more forcefully, including the possibility of downing Russian aircraft that violate sovereign borders.

The Ukrainian leadership welcomed Trump’s declaration as an affirmation of sovereignty, with Zelenskyy noting that Kyiv must be central to any negotiations.

European allies responded positively but stressed that strong commitments must be matched with tangible military and economic support.

Analysts observe that while Trump’s stance strengthens Ukraine’s diplomatic position, significant challenges remain.

Retaking Crimea in particular could prove difficult due to Russia’s entrenched presence and the complexities of international law.

Nonetheless, the statement signals a clear pivot in U.S. policy toward endorsing a maximalist outcome in Ukraine’s favor, moving away from earlier hints of compromise.

The coming months will reveal whether Washington’s rhetoric translates into concrete measures such as expanded arms deliveries, stronger sanctions enforcement, and closer coordination with NATO and European Union partners.
