According to the memo reportedly written by Pentagon policy chief Elbridge Colby – described by the network as “a noted skeptic of arming Ukraine” – the department has the power to retake arms designated for Kiev under a program known as the Ukraine Security Assistance Initiative (USAI).

While CNN sources reported that no weapons have apparently been diverted under the guidance, the policy could “rob Ukraine of billions of dollars worth of US-made materiel expected to be delivered over the coming months and years.”

The memo makes “an already murky picture of the status of US arms shipments to Ukraine” even more uncertain, the network warned, particularly given the expected meeting between Russian President Vladimir Putin and his US counterpart Donald Trump.

Under the reported memo, weapons in short supply, such as interceptor missiles for Patriot air defense systems, require direct approval from Defense Secretary Pete Hegseth before being sent abroad.

The pull-back provision is reportedly part of the same document Hegseth used last month to suspend the flow of weapons, including Patriot missiles, to Ukraine. At the time, Pentagon officials sounded the alarm over dwindling supplies at home, although Trump later ordered that shipments be resumed.

The US president has since said that American weapons could be sent to Ukraine under an arrangement in which the EU would pay Washington “100% of the cost of all military equipment.”

Despite U.S. President Donald Trump’s claim that the talks between Witkoff and Putin did not serve as a breakthrough in peace negotiations, the U.S. president announced on Aug. 8 that he will meet Putin for his first in-person encounter on Aug. 15 in Alaska.

According to European officials briefed on a call by Witkoff, Putin told Wikoff that Russia would agree to a full ceasefire if Kyiv withdrew its forces from Donetsk Oblast, giving Moscow full control of Donetsk and Luhansk oblasts, as well as Crimea, WSJ reported.

European officials briefed on the proposal reportedly expressed serious reservations about the plan, worried about the prospects that Putin is pulling along negotiations as a means to avoid punishing secondary sanctions proposed by U.S. President Donald Trump.

Additional reservations posed by European officials include a lack on clarity as to territory partially occupied by Russian forces in Zaporizhzhia and Kherson oblasts — with conflicting impressions as to whether the front line would be frozen in its current place or whether there would be a withdrawal of Russian forces in the region.

According to the WSJ, Putin’s proposal contains two phases. The first phase would entail Ukrainian forces withdrawing from Donetsk, thus freezing the front line. The second phase would entail Trump and Putin agreeing to a final peace plan that would later be negotiated with President Volodymyr Zelensky.

Ukraine currently controls the northern part of Zaporizhzhia and Kherson oblasts, as well as part of Donetsk Oblast.
