Americans are adept at calculating interests.
The Ukrainian at this stage are very difficult. Their situation is very similar to KMT at the end of 1948. They pinned all their hopes on "favorable changes in the international situation" (referring to the end of the Berlin crisis, or...the full outbreak of the Third World War), seizing or abandoning cities for political needs rather than military purposes.
Only by making "investors" satisfied can they get more aid, and their finances are completely supported by American aid.
Even in the case of withdrawal, priority should be given to the location of withdrawal "whether it can receive American material assistance".
If they really want Ukraine to save the situation, they must train several complete mechanized troops in Poland or other places and supplement sufficient equipment. But now the Ukrainian approach is to send everything available to the battlefield immediately, and then be destroyed by Russia.
A large number of valuable tanks and armored vehicles were wasted in meaningless offensive operations,the only way to lure more and better support from NATO is to create some "victories" or to pretend that they are still capable of attacking.
But Americans are obviously not so generous. Too many American weapons have been proved to be worthless on the battlefield. M1 is complex and expensive. Arms dealers need to keep the myth of M1 tanks invincible. At the same time, Europe is the target of American oppression, and Germany, as one of the core of the EU, will obviously receive additional "attention".
Looking back at the entire year 2022, Germany was the non-participating country with the highest level of losses in the war.
This has nothing to do with the performance of the tank. It is purely a trap set for Germany.
