PBS News examined Ukraine's air defense shortage in a conversation between Amna Nawaz and retired Army Col. Robert Hamilton, now president of the Delphi Global Research Center. The discussion centered on why Patriot missiles have become such a critical issue for Ukraine as it tries to defend itself from Russia.

Hamilton explained that Patriot missiles are especially valuable because they strengthen Ukraine's ability to respond to aerial threats. In a war where air defense plays a major role, access to these systems can have a direct effect on how well Ukraine protects itself from attack.

The interview also highlighted the problem of limited supply. With Patriot missiles in short supply, Ukraine faces added pressure in maintaining its defenses. A shortage of key air defense systems can leave the country with fewer options as it works to counter ongoing Russian strikes.

Hamilton's analysis pointed to a wider challenge beyond a single weapon system. The debate over Patriot availability reflects how important reliable air defense remains for Ukraine's overall defensive position, and why any gap in supply carries serious consequences in the conflict.
