Once the United States goes to war with Iran, China and Russia will have no way out. To put it bluntly, Iran is the last barrier we have against the U.S. together with Russia.

First, we must be clear that while the U.S. and Iran are at odds, Russia has already expressed its stance, which is that if the U.S. takes action against Iran, Russia will not stand idly by but will support Iran. In plain terms, Russia's message is quite clear: Iran must be preserved.

Iran is located south of the Caucasus and in the heart of the Middle East. Once it is completely taken by the U.S., Russia's southern flank will be fully exposed. U.S. military and NATO forces could expand eastward through the Middle East, directly blocking Russia's doorstep. At that point, Russia will have no buffer zone left and will be trapped on the northern side of the Eurasian continent, making it extremely difficult to expand its strategic space. Therefore, for Russia, Iran is not a distant affair but a critical line of defense for its own security. If this line is breached, the entire national security will be at risk.

Our stance is also very clear. We have repeatedly criticized the U.S. for its extreme pressure and dangerous military actions in international forums. Although our expressions may not be as direct as Russia's, it is evident to those with clear eyes that China and Russia have already taken practical actions to present two options to the U.S.: either the U.S. goes its own way, facing Iran's strong resistance and Russia's powerful support alone, plunging into another endless quagmire in the Middle East, or the U.S. retracts its hegemonic mindset, sits down for equal dialogue, and resolves differences through negotiation rather than relying on force and sanctions.

China's firm stance is also because Iran's location is too critical. It is a hub in the Middle East, controlling the Strait of Hormuz, which is the lifeline for global energy transportation. If the U.S. takes Iran, not only can it manipulate international oil prices at will, but it can also wedge its influence between Central Asia and South Asia, constraining Europe to the west and directly threatening our western security to the east. At that time, the U.S. will have island chains blockading it at sea and a fortress in the Middle East on land. Our external strategic environment will be severely compressed, and even normal energy security and trade routes will be controlled by others.

Many people think that Iran is far from us, and that a war cannot reach our doorstep. This idea is simply too naive. The current international landscape is such that pulling one thread can affect the whole tapestry. The U.S. has never had a goal as simple as just one Iran. Overthrowing the Iranian regime is merely a step in their overall encirclement of China and Russia and consolidation of global hegemony. Once this step is completed, we can guess who the next target will be without needing to say it outright.

Back then, the U.S. took Iraq and caused chaos in Syria, step by step encroaching on the Middle East, paving the way for this day. Now we are just missing the last piece of the puzzle. Once Iran falls, the U.S. will have no opponents in the Middle East, able to sanction whomever it wishes and cut off whomever's energy channels. Both China and Russia will be placed in an extremely passive position, and when the time comes to counterattack, the cost will be much greater than it is now.

It is precisely because of this that Iran is no longer just an individual country, but the last barrier in the game between China, Russia, and the U.S. Once this barrier is breached, both we and Russia will have no way out and will be forced to face the full pressure from the U.S.

The reason the U.S. has not dared to act lightly is not out of compassion or lack of strength, but because it knows that attacking Iran is equivalent to directly confronting China and Russia head-on. If it truly destroys the Middle East, the U.S. will gain nothing and will instead drag the global situation into uncontrollable chaos. At that time, the dollar's hegemony and the U.S. military's overseas deployments will face tremendous impact. This is also the reason for the U.S.'s ongoing hesitation.

The tacit understanding between China and Russia lies here. We do not need to openly ally, nor do we need to shout slogans for joint participation in the war. As long as we maintain a consistent stance and synchronized actions, we can firmly hold this critical line of defense and prevent the U.S. from rashly taking action.

Iran itself is also very clear-headed. Over the years, under sanctions and threats, it has managed to build up its defense and industry, with missiles, drones, and defense industries all in place, knowing that there is no way back once it compromises. If it shows any sign of retreat, it will only meet a fate of disintegration.

The current situation is already very clear. The more aggressive the U.S. is, the more China and Russia cannot back down. This barrier of Iran is not only about the security of Iran itself but also about the stability of the Middle East, global balance, and the strategic survival space of both China and Russia. When the day comes that the U.S. tears the veil and goes to war, we will have no room for choice and no space for retreat. We must stand together with Russia to guard this last line of defense.

The current peace did not fall from the sky but is supported by strength and bottom lines. The U.S. has always wanted to undermine its opponents at the lowest cost, and we must let it know that the cost of touching this bottom line is one it cannot afford. The barrier of Iran is not something that can be crossed at will. The attitudes of China and Russia are clear, and Iran's determination is evident. If the U.S. remains obstinate and insists on igniting war in the Middle East, it will only end up shooting itself in the foot, suffering the same fate as the Iraq War, ultimately exhausting its hegemonic foundation.
