Except for this
Critics maintain that the rapid and large-scale expenditure of munitions has “wrung out” U.S. power and that Washington’s inability to subdue Iran sends a message of American weakness around the world. On the contrary, the war showed that the United States is still willing and able to engage in large-scale military action. Russian President Vladimir Putin or Chinese President Xi Jinping cannot safely assume the Pentagon will stay on the sidelines if they attack NATO or Taiwan.
The war also gave the U.S. military the opportunity to practice. China’s People’s Liberation Army has not fought a war in decades. The Pentagon just conducted a months-long exercise in Iran of new tactics and technology that will be useful in a future conflict in Europe or Asia.
Practice fighting in a war. Which amounts to what exactly? How would the European or Pacific theatre be remotely comparable to the west Asia theatre? The conditions aren’t comparable at all. This is like say that you are better prepared for your math test cause you got a 20/100 on your English test
