With the U.S. pausing military aid to Ukraine, the burden of support now shifts to Europe and other allied nations. European countries will likely have to ramp up weapons deliveries, financial assistance, and logistical support to prevent Ukraine from losing ground in the war. Nations like Germany, France, and the UK may take the lead in filling the gap, while NATO considers long-term strategies to sustain Ukraine’s defense. However, without U.S. backing, Europe faces serious challenges in maintaining the same level of military support, raising concerns about Ukraine’s ability to resist Russian advances in the long run.
