At the end of World War II, the United States already had the atomic bomb, and the Soviet Union did not succeed in exploding the first atomic bomb until 1949. Why didn't the United States take advantage of this time lag to attack the Soviet Union, which had been badly wounded in the Soviet-German war?
Some people in the West really considered immediately attacking the Soviet Union and completely eliminating this red threat, but after weighing the pros and cons, this plan was fruitless, and it turned into decades of Cold War and several local wars.
One of the strong reasons for attacking the Soviet Union at that time was:
The Soviet Union suffered huge casualties in the Great Patriotic War, with military and civilian casualties as high as 20 million people, if the Soviet Union was attacked at this time, the Soviet Union probably did not have many reserves, so it is said that while he is ill, he will die!
According to the 1998 release of the archives, Churchill ordered the Joint Staff of the British Armed Forces to develop a plan called "Operation Incredible", which would use the Anglo-American army, the Polish exile army trained in British equipment, and recruit at least 100,000 troops from German veterans in World War II to attack the Soviet Union.

Wargame recovery of the "Incredible Operations" program
Churchill not only used such a battle plan to incite the Western camp to prepare for war, but on March 5, 1946, he also went to the United States to deliver the famous "Iron Curtain Speech" to encourage the confrontation between the United States and the Soviet Union.
However, it is believed that the rational people in the Decision-Making Hierarchy in the United States, after careful consideration, are reluctant to attack the Soviet Union, except that Churchill, an active agitator, is a foreigner, for a possible reason:
1. A well-known figure in the United States who held a similar view was General Patton, a famous General of World War II, who treated Soviet officers very unfriendly in official meetings with the US and Soviet forces at the end of the war, and made remarks about rearming the German army and then attacking the Soviet army. But Patton died of serious injuries in a bizarre car accident on December 21, 1945, whether the accident was really an accident or "arranged", in short, there was one less enthusiastic agitator to attack the Soviet Union in the US army.
(2) The Soviet Union, on the other hand, has apparently obtained various trends in the West through various channels. To this end, most of the elite troops attacking Berlin were incorporated into the German group, and in the name of the people's police stationed in the camp, the pro-Soviet German army was organized, and in the border friction between the two sides, the two sides had gains and losses, making the United States realize that it was not easy to conflict with the Soviet Union.

However, the following two points may be more important:
3. Judging from the performance of France in the Great War, it was not satisfactory, britain's army was not large, and the United States was actually the ally of the Western countries after World War II. Then the main offensive force can only be the US military.
If the United States had gone all out to conquer the Soviet Union, it would have lost both. Then Britain and France, which are slightly less powerful, will certainly restore their pre-World War I power status, and the United States is not cost-effective.
If the Soviet Union wins the war and the United States is seriously injured, France, a country that has surrendered rapidly to Germany in 40 years, may surrender again "with a quick eye".
And Britain is a master of vertical and horizontal, anti-Soviet before the war, and after the outbreak of the Soviet-German war announced its alliance with the Soviet Union, after the Stalin Campaign, Churchill held a solemn ceremony, presented stalin with the sword of Stalingrad to celebrate, after World War II and actively anti-Soviet, this country for the United States, in fact, is not reliable. The United States is still not cost-effective.

So why should the United States give up its allies in the West and pursue a very risky future?
4. There was a certain tacit understanding between the United States and the Soviet Union in the division of interests after the war, that is, to divide the British and French overseas colonies by bloodless means. In the new countries in Asia, Africa and Latin America that had emerged from colonial rule, the United States and the Soviet Union could not wait to send aid, train agents, and drive away the influence of Britain and France.
The Suez Canal incident of 1956 was one of the most influential and obvious events.
Therefore, the United States, the ally of the West, was unwilling to attack the Soviet Union, and there was no way to talk about war.
Moreover, the first atomic bomb of the Soviet Union exploded in 1949, and the Soviet Union's atomic bomb technology has a lot of information provided by informants from the United States. Later, it was pointed out that many informants did not trust or like the Soviet Union and handed over these materials, but because they were worried about the War between the United States and the Soviet Union and felt that the atomic bomb could prevent the recurrence of a world war, so they took the initiative to disclose this information to the Soviet Union.
