American military leaders have acknowledged in a recent closed meeting with Congress members that the U.S. is unable to intercept all Iranian drones targeting American installations. General Dan Caine, head of the U.S. Joint Staff, stated that while they can shoot down the majority of these drones, a significant number still evade their defenses. The use of low and slow-flying low-cost Shahed drones by Iran is particularly problematic, as these drones are designed to bypass air defense systems by flying beneath their detection capabilities.

Caine emphasized that the U.S. has sufficient precision ammunition for both offensive and defensive operations. However, he noted that the Iranian strategy is to deplete American missile reserves, such as the advanced Patriot and Thaad systems, by overwhelming them with a large volume of slow-moving drones. This tactic presents an ongoing challenge to U.S. military effectiveness in the region.

The financial toll of the conflict has also been significant for the U.S., with initial costs estimated at around two billion dollars per day, although this figure has since decreased to approximately one billion dollars per day. In the context of prolonged military engagement, former President Trump suggested in a social media post that the U.S. can sustain its military operations indefinitely, claiming nearly unlimited supplies of medium and upper medium-range weapons, indicating a commitment to maintaining U.S. presence and action in the region despite the challenges faced.
