It is said that the United States is a "war peddler" who started from war, and its growth trajectory as a superpower is sprinkled with the corpses and blood of the people of the invaded countries. However, this is in the past, and the current United States has lost its former war spirit, on the contrary, the most feared war in the world is estimated to be the United States.

The weaker the person, the more he likes to show his fierce side in order to try to deter others from attacking him. The United States is now like this, always likes to swing its fist at its opponents, trying to prove that it has the energy to wage war. But this does not mean that the United States dares to start a war; on the contrary, it is a typical manifestation of the United States' fear of war.
In stark contrast to the U.S. naval and aircraft carriers and strategic bombers, which flaunt their might in the Asia-Pacific region and Europe, U.S. forces in Japan are now trying to learn how to save their lives when they are beaten. According to the Global Network, a few days ago, the air station of the US Marine Corps Iwagoku Base located near Hiroshima, Japan, suddenly sounded an alarm, and the US servicemen stationed here received a signal of "missile attack", and all personnel were asked to "seek protection on the spot" until they were notified to evacuate.
This is not a war, but a recent exercise by U.S. Marines stationed at Iwagoku Base in Japan to simulate an air station being attacked by enemy missiles. It is reported that the "attacked" Iwakuni base is stationed with the most advanced F-35B stealth fighters of the US Marine Corps, and the US Navy's USS Reagan aircraft carrier is also docked here. If war does break out, it is likely to become the focus of the US strategic adversary. Obviously, the US military is holding such a drill to prepare for the possible "beating" in the future.
At present, the relationship between the United States and strategic competitors such as Russia is extremely tense, and there may be great power conflicts in the Asia-Pacific region or Europe at any time. In the context of a major power conflict, the U.S. military is unlikely to worry about attacks on military bases, as it did in previous wars on terror. Since it is a major power war, in the case of equal strength, the United States must prepare for the possibility of being beaten, which is the main purpose of the US military to hold such exercises.
Coincidentally, two F-18 fighter attack aircraft of the U.S. Marine Corps recently carried Harpoon anti-ship missiles into the air for training missions. In this regard, the spokesman of the US Marine Corps claimed: This kind of action will appear frequently in the future, and the purpose is to send a signal to the opponent: the US military is ready to fight at any time.
At a time when the confrontation between major powers provoked by the United States is becoming increasingly fierce and major power conflicts may occur at any time, the recent drills conducted by the US military stationed in Japan in such subjects as strikes and beatings have made it clear that they are demonstrating to Russia and other adversaries that the United States has the "determination and ability" to launch a war.
As a superpower that started with war, the United States has the ambition to launch a war, but it cannot afford the cost of a war among a major power, and it is even less able to afford the consumption of personnel and resources in a war between a major power. Otherwise, the United States would not have to launch military retaliation against Iran when the drone was shot down and the US military in Iraq launched an early missile strike, let alone withdraw its troops from Afghanistan in a hurry. It can be said that the US military is now "unable to win even the Taliban with the AK-47", and what qualifications do they have to win the war with the great powers?
What's more, the actual situation in the United States at present does not have the ability to support the Biden administration in launching a large-scale war. At present, the United States has become a terminally ill "critically ill patient" due to the mire of crisis such as political polarization, the loss of control of the epidemic, inflation and supply chain disruption. At this time, if a great power war breaks out, it will really kill the superpower.
Therefore, the fact that the US military held offensive and defensive combat exercises in Japan with great fanfare at this time does not mean that Washington has the courage to provoke a major power war. Rather, it is more of a manifestation of U.S. bravado in the hope of deterring adversaries and discouraging them from launching a military attack on the United States at this sensitive time. The reason is not complicated: Today's United States can no longer afford the attrition of war.
