US President Joe Biden has promised to support Ukraine “as long as it takes,” but neither he nor anyone else can say how long the war will last. US officials admit the US and EU stockpiles of weapons will run out at some point. Biden and his team are looking for a long-term strategy for arms shipments, as the prospect of a negotiated settlement remains remote, and the public begins to feel war-weary. According to some estimates, military aid to Ukraine, approved by Congress, will continue until the second quarter of next year. But the question is how long the current supply of arms and ammunition will last without impairing the military readiness of the US. American officials called on other countries to provide Ukraine with stocks of Soviet-made weapons, with which the Ukrainian military is more familiar.
