Broadly speaking, there are many reasons for the final defeat of the fascists in the island countries in World War II, and various internal and external reasons jointly led to the final result, but if we focus on the Pacific theater from a narrow perspective, the failure of the intelligence battlefield is the most direct cause of the defeat of the island countries.

The reason for this result is not that the secret services of the island countries are useless, but that there is a reason, and the island countries are inherently at a great disadvantage in the intelligence battlefield with the United States.

The reason is also simple, the first battlefield of intelligence warfare is infiltration, through the successful infiltration of the other party's internal spies to obtain fragmented intelligence to slowly establish a data advantage, and finally affect the front of the war, and after the war begins, the two sides will cut off the intelligence tree established through diplomacy before, so once the war starts, valuable information is impossible to obtain through conventional means such as diplomatic accumulation, in this case it is time to test the penetration capabilities of both sides.

However, because the island countries and the United States are of different races, the geographical isolation is also very far away, and the ideologies are even more different, which makes the infiltration work very difficult, but because the United States and the mainland presidential government are on good terms, the United States can send spies to infiltrate the island countries through the presidential government, and since the island countries and the mainland are both of the same race, as long as there are no mistakes in language and behavior, the success rate of infiltration is naturally much higher than that of the Americans.

The same advantage was not given to the island countries, which were originally opposed to world ideology at that time, and the island countries were even more mired in diplomatic isolation before the war because of the military hardliners' power, and in this case, the island countries had little to do to infiltrate the United States.

If it can do things for the United States, which has deep pockets and is also a spokesman for the bourgeoisie, the presidential administration will naturally go all out; the number of spies infiltrated by the military commanders into the island countries since the middle of the war was not a small number, and the efficiency of infiltration was greatly improved after the island countries began to be defeated in the later period, and by 1945, the mainland side already had a relatively complete intelligence network in the island countries.

The above-mentioned Republican Party is not very clear, because Roosevelt was re-elected too many times after taking office for the first time, and the Republican Party has been in the opposition for a long time, so it is naturally getting farther and farther away from the core secrets of the state, but now it is different, the Republican Party and the Democratic Party are equivalent to temporarily co-governing, in which the Democratic Party is in charge and the Republican Party plays a supervisory role, so the Republican Party has also begun to come into contact with some core secrets.

After the meeting, the top level of the Republican Party gave Dewey carte blanche as the chief of internal strategy to handle wartime affairs, and the first thing Dewey did after taking office was to propose that the War Department (Department of Defense) use the intelligence network of the mainland presidential government in the island country and start collecting relevant intelligence.

Although Yu Zecheng used his authority to manipulate some intelligence personnel in the island country before going to the United States, it is certainly impossible to cover everything, that is to say, the intelligence collected by Dewey is basically true and credible.

About a week later, there was a result, which was the same as Yu Zecheng expected, but it greatly exceeded Dewey's expectations.

As a result, after compiling and analyzing a huge amount of various information, we have come to the conclusion that most people in the island countries have lost their fighting spirit, and many large enterprises and chaebols such as Mitsubishi, Kawasaki, and Fuji are even looking forward to the early surrender of the island countries.

The reason for this is that the island countries have overdrawn their national strength in the war, and to put it simply, basically from the middle and late stages, the island countries do not spend money to fight wars.

Isn't it a good thing not to spend money?

It's not a good thing, on the contrary, it's a big bad thing.

To explain this, we must first understand why it costs money to fight.

It stands to reason that the government is in control of the army, the police, and other violent institutions of the state, and only needs to use administrative coercion to force domestic enterprises to produce for them free of charge, and force the people to voluntarily enlist in the army without military pay.

In fact, this is not impossible in theory, but the premise is that your overall national strength must far exceed that of your opponent.

Because in the final analysis, war is a contest of two things, one is the comprehensive resources and wartime potential of the two countries, and the other is the efficiency of collecting and extracting these resources and potential in wartime. The second of these two points is particularly important, especially very important.

Once the government starts to wage war without spending money and is unwilling to pay the cost for the transfer and collection of domestic resources, then the efficiency of this transfer and collection will become extremely low, and if you don't give money, the enterprise can grind foreign workers or cut corners, right?

How much does it cost to equip every enterprise and every army with a large number of supervisory personnel? How much does it cost to maintain the loyalty of these supervisory personnel? While you are still having a headache in recruiting resources and forming a loyal and reliable supervisory team, the enemy country has already raised N well-equipped and combat-spirited group armies early by means of spending a lot of money.

If you do the math of this account before and after, it is obvious which is more cost-effective.

What's more, the fundamental purpose of war is nothing more than to divert internal contradictions or seek development, and the result of not being willing to spend money on war will not only be unable to win the war, but will also intensify domestic contradictions to the point of no return, and the overdrawn national strength will make the country's future development even more difficult.

Since there are so many disadvantages, why does the upper echelons of the island countries follow this mode of fighting without spending money?

In fact, there are not a few countries in history that take the suicidal mode of fighting wars without spending money, and these countries generally have two characteristics, one is that this country is a religious country that integrates politics and religion, and the other is that this country has come to the verge of collapse because of the war, so it must fight with all the jade and stones, and if you win, you can still continue your life, and if you lose, you will completely withdraw from the stage of history.

The island country in 1945 was undoubtedly the second situation, when the defeat of the island country was decided, and it was meaningless to continue the war except to destroy the spiritual foundation of the nation, the enterprises were suffering under the tough measures of the military department, and the people were struggling in dire straits, and the hope of ending the war as soon as possible was the real thought in the hearts of most people.

However, the right to speak is always in the hands of a few people, when this part of the minority is mostly rational, it is the blessing of the country, and when the stupid rice bucket is the majority, it is a big deal to make the rotten wood on the temple for the official palace and the beasts under His Majesty, but when these few people are crazy, they will drive the national aircraft carrier to the abyss without hesitation......

......

After receiving this information from the island nation, the Republican top level represented by Dewey began to discuss, and the American meetings were often very efficient, and soon the Republican Party came to the conclusion that Yu Zecheng's previous proposal not to use the atomic bomb but to use atomic deterrence to force the island nation to surrender peacefully was very feasible.
