Senator Mitch McConnell warned earlier this week that the Pentagon is “not learning quickly enough” from the ongoing conflicts in Ukraine and Iran, raising concerns that America’s adversaries are adapting faster to modern warfare than the U.S. military. The Kentucky Republican expressed his concerns during a Senate Appropriations Committee hearing on Tuesday, signaling frustration with the Defense Department’s pace of adapting to battlefield innovations.
McConnell’s warning reflects months of criticism about Pentagon policies that he argues are slowing the military’s ability to absorb critical lessons from two active theaters. In an April op-ed in The Washington Post, McConnell detailed his concerns, noting that officers eager to apply Ukrainian counter-drone and electronic warfare tactics to U.S. Army preparations cannot learn from a war “if they can’t properly observe it.” The Pentagon, he wrote, continues a policy of significantly capping the number of military trainers authorized to assist Ukraine and witness the conflict up close.
The senator highlighted a stark asymmetry: while the U.S. military moves cautiously, America’s adversaries are moving aggressively. “Iran has made that painfully clear in its attacks on U.S. personnel and facilities in the Persian Gulf, which applied drone capabilities honed by Russia with deadly effect,” McConnell wrote in April. North Korea, he added, sent troops to Russia “not out of charity but for tactical experience and closer alignment with Moscow.”
The Pentagon has taken some steps to close the learning gap. The Defense Department deployed personnel to Ukraine in May 2026 to study drone combat and apply battlefield lessons for American military operations. The U.S. has also deployed drone technology inspired by Ukrainian innovations, including systems now being used in the Middle East to counter Iranian threats. However, McConnell argues these efforts remain insufficient given the scale and speed of change on modern battlefields.
McConnell’s broader concern centers on the Pentagon’s handling of congressionally authorized funding. The senator chairs the Senate Appropriations Subcommittee on Defense and has criticized the department for sitting on $400 million in military aid to Ukraine that Congress authorized in fiscal 2026. When appropriators sought explanations from the Pentagon’s policy office, led by Undersecretary Elbridge Colby, McConnell said they were “stonewalled.” The senator has argued that this funding delay, combined with restrictions on military observers, prevents the U.S. from maximizing its ability to modernize based on real-world conflict data.
McConnell emphasized that supporting Ukraine represents an investment in American security. In the first two years of Russia’s full-scale war, he noted, support for Ukraine drove billions of dollars in investments in the U.S. defense industrial base, expanding production capacity for critical munitions and components. Yet the Pentagon’s reluctance to fully engage with those lessons and fund related initiatives risks allowing competitors to gain strategic advantage.
The senator warned that China is “doubtless watching events in Ukraine” as it crafts its military investments and plans. With peer competitors and near-peer adversaries learning from these conflicts faster than the Pentagon appears willing to adapt, McConnell’s message underscores a central challenge for U.S. defense strategy: the speed of learning in modern warfare may determine military readiness in future conflicts.
