美媒：美国在中东集结的空中力量，达到2003年入侵伊拉克以来之最

Core Viewpoint - The escalating tensions between the US and Iran have led to significant military preparations by the US, including the deployment of advanced aircraft and naval forces, while diplomatic negotiations continue with limited progress [1][2][10]. Military Preparations - The US is deploying a large number of combat and support aircraft to the Middle East, marking the largest air force buildup in the region since the 2003 invasion of Iraq [1]. - Advanced fighter jets, including F-35 and F-22, are being sent to the region, along with a second aircraft carrier group and critical air defense systems [1][10]. - The US military is prepared for a sustained air campaign against Iran, potentially lasting several weeks, rather than a one-time strike [1][2]. Diplomatic Efforts - US and Iranian representatives have met in Geneva to discuss potential agreements regarding Iran's uranium enrichment, with some progress reported but significant disagreements remaining [2][6]. - Iran has indicated a willingness to compromise on its nuclear program, provided sanctions are lifted, but is unlikely to agree to a complete halt of uranium enrichment [6][12]. Strategic Considerations - The US military has overwhelming advantages over Iran, but Iran possesses a substantial missile arsenal that could target US bases and allies in the region [7][11]. - The US is considering using bases in Diego Garcia and the UK for potential military actions against Iran if diplomatic efforts fail [7][10]. Historical Context - The current military buildup is significant but still less than the forces deployed during the Gulf War in 1991 and the Iraq invasion in 2003, with fewer ground forces available for support [11]. - The lack of international coalition support and restrictions from regional allies like Saudi Arabia and the UAE complicate the US's military options [11].
