President Volodymyr Zelenskyy announced Ukraine’s readiness to purchase a substantial aid package from the United States that would serve as a security guarantee for the country.
Following the US presidential election, Zelenskyy warned that Ukraine could lose the war against Russia if American aid was reduced. In February, he stated that surviving without US assistance would be “very, very, very difficult” both during and after the war. However, the Commander-in-Chief of the Ukrainian Armed Forces, Oleksandr Syrskyi, expressed a different view, suggesting Ukraine could continue fighting even if US aid were completely halted.
By March, Ukraine reportedly received 90% of the weapons allocated under former President Joe Biden’s administration, while President Donald Trump’s administration has not yet announced new aid for Ukraine.
According to Interfax-Ukraine, Zelenskyy clarified during a meeting with journalists that Ukraine is not seeking free assistance but rather proposing a paid arrangement for critical defense equipment.
