川普親自下令!美軍空襲伊朗13天後喊停 外媒曝原因 – Yahoo新聞

The United States military has scaled back major air operations targeting positions across Iran following a concentrated 13-day air campaign, as strategic and logistical assessments prompt a shift in Washington’s approach. According to reports from the New York Times and regional news agencies, the sudden halt to the intensive bombing campaign comes as military planners evaluate operational limits against heavily fortified subterranean installations, while the White House leaves open potential diplomatic channels.

The campaign, which saw waves of precision missile strikes hit various locations throughout Iran, pushed military logistics to a critical juncture. Defense analysts note that while long-range air assets delivered heavy blows to designated command structures and logistics hubs, penetrating deeply buried, mountain-carved redoubts like the Fordow or Natanz nuclear facilities requires specialized ordnance that current operational deployments struggle to consistently deliver without unacceptable risks to aircraft and crews.

President Donald Trump ordered the military action to degrade regional proxy networks and compel Tehran toward negotiations, according to administration briefings. However, as the campaign crossed the two-week mark, discussions within the National Security Council pivoted toward the diminishing returns of a sustained air campaign against decentralized and hardened targets, leading to the abrupt de-escalation of large-scale sorties.

Evaluating Operational Limits on Fortified Sites

A central factor in the pause involves the physical limits of modern conventional air power against deeply buried infrastructure. Military experts consulted by international media outlets highlighted that certain key installations, frequently referred to in regional reporting by names such as the Fordow facility near Qom, are built deep beneath solid rock formations designed to withstand heavy penetrator munitions.

According to assessments published by defense analysts, standard tactical fighters and conventional cruise missiles lack the continuous heavy payload capacity required to completely neutralize these subterranean complexes. While the initial 13 days of strikes successfully disrupted surface-to-air missile batteries, radar installations, and Islamic Revolutionary Guard Corps logistics centers across Iranian territory, destroying hardened underground centrifuge halls remains an acute engineering hurdle for conventional air forces.

This reality forced a tactical reassessment in Washington. Rather than committing to an open-ended air campaign with high sortie rates and escalating logistical costs, military commanders recommended a pause to review target damage assessments and weigh alternative strategies.

Diplomatic Openings and Regional Reactions

Despite the intense kinetic exchanges over the preceding two weeks, the administration has maintained that diplomatic engagement remains a viable path forward. State Department officials indicated that backchannel communications via intermediary nations have continued, aimed at testing Tehran’s willingness to curb its nuclear enrichment program and halt support for regional militias.

Regional capitals have reacted with cautious relief to news of the suspension. Neighboring states, heavily exposed to potential retaliatory missile and drone strikes, had pressed Washington behind closed doors to avoid a prolonged regional conflagration. Energy markets, which experienced sharp volatility during the initial days of the airstrikes, stabilized following reports of the operational halt.

Iranian state media acknowledged the cessation of heavy air raids while maintaining a defiant posture, claiming that the country’s defensive infrastructure weathered the assault successfully. Independent verification of damage to specific military sites remains difficult due to strict information controls imposed by Tehran.

Next Steps and Monitoring Official Updates

The current pause marks a fluid transition phase in Washington’s Middle East strategy, shifting from active combat operations to a posture of watchful deterrence and diplomatic probing. National security advisors are expected to brief congressional leaders on the outcomes of the 13-day campaign and outline long-term monitoring protocols.
