Donald Trump announced on September 3 that he will request European countries to repay the military aid and ammunition the United States provided to Ukraine during the Russia-Ukraine conflict under the Biden administration [1, 2, 3]. Trump said "Hundreds of Billions of Dollars was given to Ukraine and Nato, free of charge, that Europe would have paid for — If they were only asked, but we will be asking for that money, though somewhat belatedly!" [4]. He claimed that Europe financed weapons for Ukraine through the US-NATO 'Prioritized Ukraine Requirements List' but that the Biden administration did not demand repayment from Europe earlier [1, 2, 3].

Trump criticized the Biden administration for delivering large quantities of aid without requiring payment from European allies, despite the cost reaching hundreds of billions of dollars [1, 2, 3]. He denied reports suggesting the US military is running low on ammunition amid conflicts including the war against Iran, stating, "We have virtually unlimited amounts of Mid to High Grade Ammunition. We are taking (munitions) for ourselves, the U.S.A., rather than selling them to others, but the sales to Allies will soon again, begin" [1, 4, 2, 3].

Reports surfaced in August that the US Army had largely depleted much of its high-precision long-range missile stockpiles during the conflict with Iran, raising concerns about military readiness [1, 3]. The strikes included the destruction of 14 missile launchers [3]. Despite these reports, Trump emphasized that ammunition production is at unprecedented levels and sufficient for US needs [1, 4, 2, 3].

US Treasury Secretary Scott Bessent noted the economic effects of the ongoing conflicts, saying the wars in Ukraine and Iran have triggered an energy shock due to Ukraine's targeting of Russian energy assets, leading to global price pressures [1]. These tensions may affect the Republican Party's efforts to retain control of both chambers of Congress in next year’s elections [1, 2, 3].

Trump said the US has temporarily suspended arms sales overseas but expects to resume sales to allies soon [1, 4, 2, 3].
