Retired U.S. General slams U.S. delay in fighter transfers to Ukraine

Retired U.S. Air Force Lt. Gen. David Deptula criticized U.S. policy on military assistance to Ukraine during a Substack Live podcast hosted by military historian Phillips P. O’Brien, arguing that Washington delayed providing key combat capabilities early in the war because American leaders were deterred by Russian rhetoric.

Deptula said “one of the biggest mistakes that the allies fell into, primarily the United States, under both Presidents Biden and Trump,” was that U.S. leaders “have been inhibited by Putin’s rhetoric and deterred from providing Ukraine” what he described as the ability to strike effectively early on.

In the podcast, Deptula framed his criticism as a lesson learned about the pace and scope of assistance. “And one of the biggest mistakes that the allies fell into, primarily the United States, under both Presidents Biden and Trump,” he said, “is they have been inhibited by Putin’s rhetoric and deterred from providing Ukraine very early on” with the capability he believes could have altered Russia’s maneuver plan.

Deptula described that capability as “the ability to strike rapidly and deeply to confound the Russian scheme of maneuver,” adding that “we could have done in the first year of the war and put this thing to an end already.”

The discussion also touched on combat aircraft and what additional platforms could mean for Ukraine’s air operations.

Deptula said, “Imagine what the Ukrainian Air Force could do if they had a wing of F-35s.” He added, “You give me a wing F-35s, a wing F-22s, and this thing would be over in a month.”

He later referenced F-16s, saying, “Those F-16s have got some Ukrainian pilots who got upwards of 100 kills.”

His comments were presented as an argument about airpower’s potential to shift battlefield dynamics faster than incremental upgrades, though the transcript does not provide supporting evidence for specific claims about pilot tallies.

From an operational standpoint, Deptula’s critique focuses on the difference between providing defensive systems and providing tools that can impose costs at range.

“Strike rapidly and deeply” generally means the ability to hit command posts, logistics nodes, air defenses, and other operational enablers beyond the front line. In airpower terms, that can involve aircraft, standoff weapons, targeting networks, and intelligence support that enable time-sensitive strikes.

Supporters of earlier aircraft transfers often argue that fighters are not just about air-to-air combat. They can carry precision-guided munitions, support suppression of enemy air defenses, and expand a force’s ability to respond quickly to emerging targets. Critics typically point to training, sustainment, basing vulnerability, and escalation management.

Deptula’s remarks fit into that broader military logic, but his specific claim was political and strategic: he said U.S. leaders were “deterred” by Russian rhetoric and that the result was delayed delivery of capabilities that could have produced earlier effects.

The debate over fighter aircraft for Ukraine has repeatedly surfaced alongside other high-end categories of support, including long-range strike, air defense, and intelligence-enabled targeting.

Deptula’s criticism is not framed as a partisan point about one administration alone. He explicitly names “both Presidents Biden and Trump” while arguing that fear of escalation constrained policy choices.

That framing is likely to resonate across the defense policy space because it suggests the same caution persisted across leadership changes, rather than being tied to a single decision or moment.

Deptula is arguing that speed and depth of strike options can shape an enemy’s ability to maneuver and sustain combat operations, and that delaying those options can prolong a war. His criticism matters because it targets the decision calculus behind high-end transfers like fighter aircraft and related strike capabilities, and it highlights a core military problem: whether Ukraine receives tools that primarily defend against attacks, or tools that also impose costs at range in ways that can disrupt Russian operations.
