How should the seven Nazi allies rank according to their combat effectiveness?

During World War II, Nazi Germany had seven allies, namely, Italy, Japan, Bulgaria, Romania, Finland, Hungary, and possibly Thailand, which is not clear to everyone. So what was the ranking of the combat effectiveness of these seven countries at that time?

First of all, there is no doubt that the weakest country must be Thailand. Thailand was not called Thailand during World War II. At that time, their names were Siam. Siam was forcibly drawn into the German camp by the Japanese. During the whole World War II, it appeared in people's field of vision as a Japanese younger brother. When other countries began to use tanks, they were still using elephants as heavy weapons ... it is conceivable how weak the fighting capacity of this country is.

There is no doubt that the strongest country should be Japan, even Mussolini's Italy can't compete with it. In fact, the fighting capacity of Japan at that time did not know how many streets were dumped in Italy. At most, Italy has become the king of North Africa with its advanced weapons and equipment. It is not surprising that they later became the first of the three fascist countries to surrender. In fact, during the whole World War II, the Italian army made many jokes.

On the other hand, Japan is different. Throughout World War II, Japan relied on the strength of one country to basically compete with the whole of East Asia and Southeast Asia. Even in the late World War II, a large part of the troops were assigned to fight the Pacific War with the United States. Once fought to the death with the United States, Americans suffered greatly. Therefore, there should be no doubt that Japan is the boss among these seven allies.

Of course, compared with Germany, Japan's combat effectiveness is not to mention. During World War II, Germany fought against all major European countries alone. If it weren't for the heavy snow and cold in Moscow, the fate of the Soviet Union at that time would be hard to say.

As for several other countries, their combat effectiveness is comparable and not much stronger.
