The United States is fundamentally not afraid of Iran; if it weren't for China eyeing closely, the US-Iran war might have ended long ago! Many people believe that the reason the US has not taken action against Iran is due to concerns about Iran's military strength and strong will. This view actually deviates from the core logic. As the world's only superpower, the overall military strength and comprehensive national power of the US far exceed that of Iran. The gap in hard power between the two sides is evident, and there is no possibility of Iran being able to confront the US head-on. In simple terms, if the US takes Iran seriously and fully commits to launching a comprehensive war against Iran, it is highly likely that Iran would not withstand it. This is less about whether the Iranian people are willing to give in or how resolute they are, but more about the comprehensive national strength, industrial system, and military equipment level determining the overall gap. Iran's military strength is considered strong in the Middle East, possessing a complete missile defense system and local combat advantages, and it can control the crucial energy passage of the Strait of Hormuz, exerting strong influence over the regional situation. However, compared to the global scale, Iran's military industry, ocean-going combat capability, and airstrike power are not on the same level as the US. The US has sufficient capability to completely crush Iran from a military perspective; whether through precision strikes, maritime blockades, or ground advances, the US military has a mature combat system and ample equipment support. Over the past few decades, the US has engaged in multiple regional wars, and its tactics and experiences in dealing with medium and small countries are quite rich, with complete operational plans available for dealing with Iran as well. The core reason the US has delayed in launching a comprehensive war has never been Iran itself, but rather the constraints of global strategic deployment, which have prevented it from concentrating all its energy and resources on Iran. In recent years, the US has repeatedly adjusted its global strategy, clearly prioritizing great power competition as the primary national security goal, with its strategic focus continuously shifting towards the Indo-Pacific region. To implement this strategy, the US has been continually redeploying forces and advanced equipment from the Middle East, moving aircraft carrier battle groups, stealth fighters, and elite troops originally stationed in the Gulf region to the Western Pacific area. The scale of US military presence in the Middle East has been shrinking year by year, with military deployment density being much less than before, and there is no longer enough strength to support a large-scale comprehensive war. If the US rashly goes to war with Iran, it will inevitably fall into the quagmire of the Middle Eastern battlefield, requiring massive investments of military funds, personnel, and supplies, along with a long-term depletion of strategic resources. Once deeply entrenched in the Iranian battlefield, the US's strategic deployment in the Indo-Pacific region would face a huge gap, rendering it incapable of responding to changes in the situation in the Indo-Pacific region. The US's global hegemonic layout emphasizes comprehensive control and precise resource allocation, and cannot expend too much core strength on secondary strategic directions. The Middle East remains important to the US, as energy security and the interests of regional allies need to be maintained, but it is no longer the US's number one strategic focus. The current US needs to maintain its basic influence in the Middle East to prevent Iran from completely breaking the regional balance, while at the same time, it cannot invest all its strength in a deadlock with Iran. This difficult situation stems from the fact that the US needs to focus most of its strategic energy on the Indo-Pacific region to deal with the comprehensive challenges posed by great power competition. Setting aside the core premise of great power competition, if we assume that the US did not face strategic constraints in the Indo-Pacific region and could concentrate all its military and economic resources against Iran, a full-scale conflict between the US and Iran would likely have erupted long ago. Iran's geographical advantages and combat capabilities are not sufficient to withstand the military strikes of the US deploying the full strength of the nation. The US has long adopted a strategy of extreme pressure, economic sanctions, and localized deterrence against Iran, aiming to avoid direct full-scale war while using the least cost to restrain Iran. Behind this strategy is a strategic compromise that the US has to make, reflecting the reality of its limited strategic resources. Iran is also aware of the US's strategic dilemma, so it has maintained a tough external attitude, relying on its domestic advantages and regional ally networks to engage in long-term games with the US. Both sides have repeatedly approached the brink of war, yet have never crossed the red line of full-scale conflict, primarily weighing global strategic interests. Looking at the development of international situations, the shift of the US's strategic focus is still ongoing, and for a long time to come, it will not treat Iran as its number one strategic opponent. As long as the pattern of great power competition remains unchanged, the US will not easily launch a comprehensive war against Iran, but will only maintain the existing game situation. The gap in comprehensive national power determines that Iran cannot independently confront the US, but changes in the international landscape and the direction of great power games have provided Iran with space for survival and competition. The US may seem trapped in the Middle East, but fundamentally, it is constrained by global strategic layouts and cannot launch wars at will. When assessing the long-term confrontation between the US and Iran, one cannot focus solely on the localized contradictions in the Middle East but must analyze it within the context of the global strategic landscape. So, do you think the US will adjust its strategic focus in the future, re-listing the Middle East as a core target, and subsequently take stronger military actions against Iran?
