Overview of Lloyd Austin on Ukraine, Iran and the lessons of war
In this Financial Times Rackman Review interview, former US Defense Secretary Lloyd Austin discusses how war is changing in the drone-and-AI era, what the conflicts in Ukraine and Iran reveal about modern combat, and why he believes the US military remains strongest when it stays merit-based and nonpolitical. He also reflects on his warning call to Russian Defense Minister Sergei Shoigu during the early Ukraine war, and on the importance of NATO and US forces in Europe.
Key Themes
Drones are reshaping the battlefield
Austin argues that drones are not just an incremental tool but a fundamental shift in warfare.
- They allow weaker or less wealthy states to create “mass” at very low cost.
- They improve battlefield visibility, making it harder for forces to maneuver without being detected and targeted.
- Ukraine has been especially adaptive, rapidly innovating with drones, unmanned ground vehicles, and low-cost interceptors.
- Iran and Russia have also exchanged drone know-how and intelligence support.
Ukraine is becoming a laboratory for rapid military innovation
Austin says Ukraine’s innovation cycle is extraordinarily fast.
- Battlefield lessons can be incorporated in about two weeks.
- Ukraine has used drones not only defensively, but also to strike Russian infrastructure, especially oil assets.
- The war shows that cheaper, expendable, autonomous systems can offset some traditional military advantages.
The balance sheet of defense is badly tilted
A major concern Austin raises is the cost asymmetry between attack and defense.
- Expensive missile interceptors are being used against drones that cost a tiny fraction as much.
- This is unsustainable unless militaries develop low-cost layered defenses.
- He says the US must combine high-end defenses with cheaper counter-drone systems and better command-and-control.
AI is already important, but humans should remain in the loop
Austin says AI is already proving valuable, especially in intelligence analysis.
- It speeds up the processing of large volumes of data.
- It helps analysts identify critical targets or patterns quickly.
- For lethal weapons, however, he supports keeping a human decision-maker involved.
- He distinguishes between systems that need to react in seconds, like counter-rocket systems, and weapons where human judgment should remain central.
Iran, Ukraine, and strategic escalation
Iran’s capabilities and targeting strategy
Austin notes that Iran has used drones effectively and has broadened its targeting beyond military sites.
- Early Iranian attacks also targeted economic infrastructure and tourism.
- Precision depends heavily on intelligence, including satellite data.
- He suggests Russia likely helped Iran with intelligence support, and that Chinese satellite data may also have been involved.
The Strait of Hormuz remains a critical concern
Austin says he was not surprised by the possibility of Iran trying to disrupt the Strait of Hormuz.
- He calls it an international waterway through which about 20% of global energy supplies flow.
- He argues the world must prevent Iran from controlling or threatening it.
- He also questions whether the current US response reflects a strong enough interagency strategy.
On Russia and the nuclear danger in Ukraine
Austin recalls his phone call with Shoigu as a serious and necessary warning.
- He says Russian nuclear saber-rattling had become dangerous and irresponsible.
- The goal was to make clear that escalation would be taken extremely seriously.
- He describes the exchange as civilized but very serious.
Pentagon politics and the “woke” accusation
Austin responds sharply but calmly to Pete Hegseth’s claim that the Pentagon had become “woke.”
- He rejects the idea that the US military is being run on the basis of race or gender quotas.
- He argues the military is still a meritocracy and one of the best-trained forces in the world.
- He warns that politicizing promotions or firing senior officers for ideological reasons could corrode military culture.
- In his view, the armed forces should reflect the diversity of the country while still prioritizing competence.
NATO, Germany, and Europe’s security
Austin strongly defends the US military presence in Germany and US commitment to NATO.
- He says US forces in Germany still provide real strategic value and operational options.
- NATO remains, in his view, the most successful defensive alliance in the world.
- He notes that allies have increased defense spending, which strengthens the alliance.
- He rejects the idea that America should simply withdraw from Europe.
What Europe should take away
Austin says Europeans should remain vigilant about Russia.
- He believes Putin remains a serious threat, even if Russia has struggled in Ukraine.
- He warns Russia could still go after “lower-hanging fruit,” especially vulnerable frontline states.
- Countries like Estonia, Latvia, and Lithuania have good reason to stay alert and keep building their defenses.
Main Takeaways
- Drones are now central to modern war, not a sideshow.
- Cheap autonomous systems are challenging expensive legacy military platforms.
- AI is already transforming intelligence work, but human judgment should remain essential in lethal decisions.
- Ukraine’s adaptability is one of the clearest examples of modern battlefield innovation.
- Merit and nonpoliticization remain, in Austin’s view, core strengths of the US military.
- NATO and US forces in Europe are still strategically important.
- Russia remains a long-term threat, even if its performance in Ukraine has been poor.
Notable Insight
“What can be seen can be engaged, and what can be engaged can be killed.”
Austin uses this idea to explain why drones and persistent surveillance have made maneuver warfare much harder and why militaries must adapt quickly to survive on the future battlefield.
