Let me call you a liar then and let me also say: the US didn`t officially threaten the USSR with nukes while Soviets didn`t have them
Huh? I mean are you serious?
The United States State Department, on their own website, disagrees.

Will you argue with the foreign ministry of the United States about what they did or did not do?
Here's some quotes, from a source that is most incentivized to deny that the US ever used "atomic diplomacy" to force the Soviets to back down:
During the Berlin Blockade of 1948-49, President Truman transferred several B-29 bombers capable of delivering nuclear bombs to the region to signal to the Soviet Union that the United States was both capable of implementing a nuclear attack and willing to execute it if it became necessary.Same State Department page, says that some policymakers had made the argument that the United States bombed Nagasaki and Hiroshima, not because they wanted to force Japan to surrender (they were on their last legs anyway, and the Soviet invasion into Hokkaido was imminent), but because they wanted to demonstrate to Stalin what a terrible weapon they had acquired. This also prevented the Soviet Union from making any claims on Japan, and as a result Japan was under sole American occupation for the next decade.
You can read about Iran and Turkey in other places.
After we got the bomb ourselves, they continued to try to threaten us during the Korean War and then after the Cuban Revolution.
Only when we began to have more atomic weapons than them, did they cease to threaten us outright on a regular basis.
