Vladimir Putin will keep driving the war forward wider and deeper if he is not stopped, Ukraine's President Zelensky has warned.

Speaking at the UN's General Assembly in New York, Zelensky said more countries would be met with Russian aggression unless allies displayed a united front and ramped up support.

He emphasized the threat of a global arms race as military technology advances, declaring that weapons decide who survives and calling for global rules on AI.

His comments follow a shift in US President Donald Trump's stance on the Russia-Ukraine war, indicating Ukraine could reclaim all its territories.

Zelensky criticized international institutions, suggesting they are too weak to assure Ukraine's safety, reminding that membership in military alliances like NATO does not guarantee security.

He stated, We are now living through the most destructive arms race in human history, and argued that halting Russia's advances now is cheaper than facing potential threats of nuclear warfare.

On Moldova, Zelensky expressed concern that failing to act could allow Russian influence to seep into the region, emphasizing that the West missed opportunities to save Georgia and Belarus from similar fates.

In recent geopolitical tensions, incidents of Russian military aircraft breaching NATO member airspace have heightened fears, drawing further calls for a collective response based on Trump's suggestion for military actions to counter Russian threats.
