If you talk about the United States, you will definitely remember its recent series of operations on the epidemic. However, the US military's series of operations are even more indifferent. However, we cannot deny that the United States still follows the "that set" after the Cold War at the strategic and technical levels. For example, when the research and development of new equipment and new technologies, it deliberately leaks technical indicators and raises the indicators. At the same time, at least three to four fake projects are published or very easy to obtain... Therefore, when facing the information released and received by the United States, we need extremely strong relevant knowledge to keep pace with the times and make relative analysis when needed.
After entering the 21st century, even before the US military embarked on a evil path. This evil path does not lie in the technical and so-called strategic levels, but in the US military's R&D, technical reserves, project demonstration, funding and political levels.

When the concept of "military industrial dollar" was determined, the United States embarked on a "road of no return"... We can see that the US Navy's F-14 was replaced, the Militia 3 ballistic missile was cut, the F-117 stealth bomber was dismantled, the "Crusader" artillery project was dismantled, and even NASA's space shuttle and the US independent manned spacecraft disappeared. Today, the main force of US carrier-based aircraft is F-15, the Militia 3 is still in service, the B-52 is still the main force, and the main force of US Army artillery is still the M109... And the future of manned space flight in the United States requires a private company SpaceX or Boeing to operate. We do not know whether this is a result of political correctness or superior system, but we can see clues in the United States at a series of "interference in other countries' internal affairs".

At the same time, the United States developed the concept of "littoral combat ship", which is what we now know about DDG-1000 and LCS "independent" and "freedom". Starting from 1996, after the 21st century, my country began mass production of 022... But since 2008, my country's economy began to rise exponentially. The United States will find that the "littoral combat ships" developed by the "offshore navy" with small missile boats as the main body are unable to meet the needs of the US Navy when facing many large surface ships, , and cannot meet the needs of the US Navy! Although some large ships like Burke 3 appeared in the US Navy after the 21st century, they still cannot meet future needs. But it is undeniable that if there were no such epidemic at this time, many aircraft carrier battle groups of the US Navy would still be afraid of!

At the army level, it has long had no effective field air defense system and electronic warfare system, and it relies entirely on the advantages of the air force. Even if it has the most "Abrams" on the earth, it cannot save the overall situation... What's more, the US military is far inferior to China and Russia in the construction of artillery units. At the same time, we should note that a large number of active-duty officers and non-commissioned officers of the US military carry out missions against terrorism. When facing a great power war, such as in Ukraine's war against Russia, the US military staff regarded the Russian army as the Taliban and made a series of wrong decisions.

Air force level US military belongs to conservatives, and its fighter jets from the past century are the main body. Of course, this is not something the US Air Force can decide, but the US Congress. Although there are products represented by F-22 and F-35, in general, the combat effectiveness of these two fighter jets in practical applications still cannot meet the future needs of the US military. The data links of the F-22 and F-35 cannot be connected to other combat platforms. Although new methods are being developed to solve this problem, it will undoubtedly be time-consuming and labor-intensive. In addition, the maintenance problems of a large number of old fighter jets in the US Air Force, the selection of various new ammunitions, and the shortage of pilots and ground maintenance personnel have all caused headaches for the US Air Force.
And as for NASA, this actually involves the US Space Force. Due to the relaxation of the US immigration policy in recent years, a large number of foreigners have flocked to the United States. The side effects of NASA are more obvious. For example, although PTT is done well in a certain country, these people will still suffer unfair treatment when facing actual technology research and development and Congressional allocations. In addition, the so-called "market freedom" in the United States and the difficulty of having an opponent after the collapse of the Soviet Union, which undoubtedly aggravates the Americans' arrogance.Since the space shuttle dismounted, American astronauts have been able to enter the International Space Station on Russian spacecraft for a long time. Other aerospace projects are difficult to achieve results transformation, and they do not have an advantage in market competition.

We can see many problems within the US military through the above, but what makes the US military even worse is because of "politics". You may still remember the acting Secretary of Defense Shanahan in 2019. This acting Secretary of Defense had worked for Boeing for many years, so during his tenure as Trump's administration, he "treats" Boeing's old rivals and "opens the back door" for his old boss Boeing. The acting defense secretary even insulted the staff of Lockheed Martin in public, claiming that the F-35 fighter was garbage! However, fortunately, many accidents and other internal accidents of Boeing 737 MAX series passenger planes were exposed one after another. Otherwise, the "insider" sent by Boeing still didn't know what to do with the US military...
However, some products provided by some Boeing companies have problems now. For example, the KC-46 tanker is not as good as the old KC-135 in various performance indicators, and the failures occur frequently; the " Star Airliner " manned spacecraft concealed the failures during NASA test, and the failures occurred frequently during flight tests, and even "hang in reverse gear forward"...
