Europe must continue supporting Ukraine as U.S. aid declines – Polish expert

The article describes a major shift in how Ukraine receives military support. The United States has suspended aid, while European countries are becoming the main financial backers. This matters because Ukraine still needs weapons to defend itself, and the war directly affects Europe’s security, according to Polish expert Stanisław Koziej.

The new mechanism is indirect U.S. support. The United States sells weapons to European countries, and those countries transfer the weapons to Ukraine. Koziej says Europe is already shouldering the main financial burden. European governments therefore serve as the immediate channel through which some U.S.-supplied weapons reach Ukraine.

This arrangement also exposes serious limits. European stocks of some air-defense systems are small, while U.S. stocks have been largely depleted. Koziej argues that Europe must continue supporting Ukraine, because allowing Russia to seize the country would create what he calls a catastrophe for Europe.

Patriot systems are ground-based air-defense platforms that use radar, command equipment, and interceptor missiles to defend against airborne threats. PAC-3 missiles are specialized Patriot interceptors, especially important for engaging ballistic missiles. The article highlights them because Ukraine needs stronger protection from missile attacks.

A Patriot battery detects and tracks a threat, then launches an interceptor toward it. PAC-3 missiles use guidance systems to collide with or destroy the incoming target. This makes the system valuable for defending important areas, although the article focuses mainly on the scarcity of the missiles and systems.

Koziej calls the shortage Ukraine’s most pressing problem. Europe has few Patriot systems, and U.S. stocks are largely depleted. The article says Ukraine needs more air defense and may have to increase domestic production rather than depend entirely on limited foreign supplies.

The article does not provide a numerical inventory of Patriot systems or PAC-3 missiles. It gives only a broad comparison: Europe has few Patriot systems, and U.S. stocks have been largely depleted. That makes the available supply much smaller than Ukraine’s battlefield requirements.

The key mechanism is scarcity. Patriot systems need compatible interceptor missiles, including PAC-3 missiles, to engage serious airborne threats. If allies have limited systems or missiles available, they cannot quickly provide Ukraine with unlimited protection. The article identifies this shortage as the most pressing problem facing Ukraine.

The exact gap remains unspecified. There is no figure for Europe’s total, the remaining U.S. stock, Ukraine’s current inventory, or Ukraine’s precise requirement. Koziej’s proposed response is to increase Ukraine’s domestic air-defense production, which he believes could happen faster than European industrial expansion.

When air-defense missiles are scarce, Ukraine has fewer chances to intercept incoming missiles and other airborne threats. That can leave cities, troops, power facilities, and other critical sites more exposed. The article does not list specific damage or casualty outcomes, but it calls the shortage Ukraine’s most pressing problem.

The key mechanism is limited defensive coverage. Patriot systems and PAC-3 missiles cannot protect every location at once, especially when stocks are small. Commanders must use available systems where the threat is greatest. A shortage also makes it harder to replace missiles after they are fired, reducing sustained protection over time.

The current reality is especially difficult because Europe has few such systems and U.S. stocks are largely depleted. Koziej says Ukraine should expand domestic production. He believes Ukraine could build air-defense capacity faster than European countries can develop the industrial base needed to meet its needs.

The Polish expert frames the war as a European security issue because its outcome could affect the safety of countries across the continent. In his view, Ukraine’s defense is connected to Europe’s own security. That is why he says Europe has no right to abandon support.

Koziej’s central warning is direct: if Putin seizes Ukraine, the result would be a catastrophe for Europe. His argument links military assistance to prevention. Supporting Ukraine helps stop that outcome, while withdrawing support could create wider danger. The article does not detail a specific attack or threat beyond this warning.

Europe is already carrying the main financial burden as U.S. aid has been suspended. European countries are buying weapons from the United States and transferring them to Ukraine. Despite difficult stocks of air-defense equipment, Koziej says Europe must continue supporting Ukraine rather than give up.

Domestic production could give Ukraine a faster path to more air-defense capability. The article says European countries would need time to develop the industrial capacity required to meet Ukraine’s needs. Ukraine, already directly involved in the war, may be able to organize production more quickly.

The key mechanism is industrial speed. Waiting for European factories and supply chains to expand could delay deliveries. Building systems inside Ukraine could shorten that path and allow production to respond more directly to battlefield demand. The article does not name specific Ukrainian factories, designs, or production targets.

This approach would not remove the immediate shortage. Europe has few Patriot systems, and U.S. stocks are largely depleted. However, Koziej believes Ukraine can increase domestic production faster than European countries can create the necessary capacity. That could provide a more sustainable source of air-defense equipment over time.

Modern air-defense systems first use radar and other sensors to detect an aircraft or missile. Computers estimate its direction, speed, and likely path. Operators and automated systems then decide whether the object is a threat and select an appropriate response. This process matters because defenders have very little time.

After tracking the target, the system launches an interceptor. The interceptor receives guidance during flight and uses its own sensors or commands to move toward the target. It then destroys or disables the incoming object, often by striking it directly or detonating nearby. Patriot systems use this general detection, tracking, and interception sequence.

The article specifically mentions Patriot systems and PAC-3 missiles but does not describe their technical operation. It says Europe has few such systems and U.S. stocks are largely depleted. That shortage limits Ukraine’s ability to obtain more defensive coverage, increasing pressure for domestic production.
