The "confrontation" has gone on since 1945 ...
You are too young or you missed your history classes. The leftists in the USA were kissing the ass of the Soviets during the so-called "Cold War".
Leading American financial experts were Russian spies and neo-Commies.
Harry Dexter White (October 9, 1892 – August 16, 1948) was an American economist and senior
U.S. Treasury department official. Working closely with the Secretary of the Treasury
Henry Morgenthau, Jr., he helped set American financial policy toward the
Allies of World War II while at the same time he passed numerous secrets to the Soviet Union.
[1] He was the senior American official at the 1944
Bretton Woods conference, that established the postwar economic order.
He dominated the conference and imposed his vision of post-war financial institutions over the objections of
John Maynard Keynes, the British representative. At Bretton Woods, White was a major architect of the
International Monetary Fund and
World Bank.

Bolsheviks were financed by American banksters, American financial elite was supporting the Commie-Ideology, because this was a globalist ideology. Banksters dream about a world without national identities, without boarders, ruled from one place, and Communism is a good instrument to achieve this goal.
Stalin helped to create Israel (he voted for the Partition Plan with 5 votes (Russia, Ukraine, Belorussia, Poland, Czechoslovakia) without Stalin they would not have the majority for the Partition Plan. Stalin was the first leader who de jure recognized Israel as a state, he also helped Israel with weapons and military experts in a very critical period.
But after Stalin did his job, Zionists decided that they do not need him any more.
So no, the confrontation with the Soviet Union begins not in 1945, it begins in 1947, after the Partition Plan was already proclaimed.
Morgenthau boys tried to provoke a Communist uprising in occupied Germany, there is not other explanation for their sadistic plan.
Morgenthau had been able to wield considerable influence over
Joint Chiefs of Staff Directive 1067. JCS 1067 was a basis for U.S. occupation policy until July 1947, and like the Morgenthau Plan, was intended to reduce German
living standards. The production of
oil,
rubber, merchant ships, and aircraft were prohibited. Occupation forces were not to assist with economic development apart from the agricultural sector.
...
In view of the continued poverty and famine in Europe, and with the onset of the Cold War which made it important not to lose all of Germany to the communists, it was apparent by 1947 that a change of policy was required.

But, nevertheless, the former allies of WWII supported each others even during the Cold War. For example, the West supported the lie about the Katyn massacre.
In 1951 and 1952, with the
Korean War as a background, a congressional investigation chaired by Rep.
Ray Madden and known as the Madden Committee investigated the Katyn massacre. It concluded that the Poles had been killed by the Soviet NKVD
[23] and recommended that the Soviets be tried before the
International Court of Justice.
[66] However, the question of responsibility still remained controversial in the West as well as behind the
Iron Curtain. In the United Kingdom in the late 1970s plans for a memorial to the victims bearing the date 1940 (rather than 1941) were condemned as provocative in the political climate of the
Cold War. It has also been alleged that the choice made in 1969 for the location of the
Byelorussian Soviet Socialist Republic war memorial at the former Belarusian village named Khatyn, the site of the 1943
Khatyn massacre, was made to cause confusion with Katyn.
[76][77] The two names are similar or identical in many languages, and were often confused.

The Brits claim that they started WWII because of "Poland's freedom", but they did not mind Stalin's occupation of Poland, and they supported the Soviet lie about Katyn even during the confrontation, which was spitting in the face of Poles.
So American neo-Commies hated Soviet Russia after WWII not because of the Communist ideology, but because of Russian Nationalism. Stalin had to revive Russian Nationalism, because he realized that he would lose the war with his Commie Ideology. Russians were not ready to die for this Commie- Garbage, and that was the reason why his "Russian" agitator,
Ilya Ehrenburg, started an anti-German propaganda, which was based on instigating of racial hatred towards Germans.
After WWII Stalin tried to ban Russian Nationalism, but it was too late.
Communism was dead after WWII, Russian Nationalism was on the rise in the Soviet Union, and that was the reason for the confrontation between the Soviet Union and the neo-Commies in the West, who subverted American Academia, financial institutions and eventually both parties.
... reined back by Bush the Elder until Bush the Younger started giving in.
That statement is another proof that you missed your history classes.
The Soviet Union collapsed during the Reagan administration, and there was a Honey Moon in the relations between the USA and Russia. During the Yeltsin Era Russia was de facto ruled by American banksters and "Russian" Oligarchs. Bush the Elder came to power in 1989, Yeltsyn ruled from 1991 to 1999, this time Russia and USA did not have any confrontations.
Russian economy and state was in dismal conditions, Russian people were dying, the richness of the country was stolen by "Russian" Olygarchs, but the neo-Commies in the USA talked about "Russian democracy".
The confrontation with Russia began after Putin imprisoned some "Russian" oligarchs, who had stolen what belonged to the Russian people.
That was the turning point in the relations between the USA and Russia.
Obama said "no" and Putin has never stopped crying since.
Obama is just a Black Puppet in the hands of the neo-Commie puppeteers, who hate white Christians in Russia and the USA and dream about a world without boarders. These guys hate USA as much, as they hate Russia, they hate national states and national identities per se (Israel is the only exception, Israel has the right to exist as an ethno-centric "Jewish Sate")
I hope that Trump will end the crazy confrontation between the USA and Russia.
Russians and Americans will join efforts and make their Christian countries great again. Europe will only win from good relations between Russia and the USA. European economy is suffering more from this crazy confrontation, than Russian economy. Russia is self sufficient, they can sell their goods to China.
