The closest we came to a nuclear confrontation with Russia that I know of, was under John F. Kennedy during the Cuban Blockade in 1962.

Because if the U.S fought Russia with nuclear missiles (which they both had) it would destroy the world.
A blockade was considered an act of war.
The placement of U.S. nuclear missiles in Turkey is thought to have provoked the Cuban Missile Crisis. Missiles in Turkey were close enough to strike Moscow, so Russia placed armaments in Cuba, which was within striking distance of U.S. soil. The Missile Crisis, began on October 14th 1962. Robert Kennedy said, during negotiations with the Russians that the missiles would be removed within a short time after the crisis ended. The Missile Crisis ended on October 28th of 62 and the missiles were quietly taken out of turkey some time after April 24th 1963.
The United States currently owns 9,600 nuclear weapons, while Russia currently owns 16,800. But Russia actually always had more nuclear weapons than the United States. Russia was lacking in nuclear warheads from beginning of time to 1975. For various reasons, the USSR (and now Russia) have pretty much always had more ICBM weapons than the US, while the US maintained a larger stockpile of gravity bombs, SLBMs, and cruise missiles. Currently, as nuclear-tipped cruise missiles were forbidden under the START I treaty, only bombs, ICBMs, and SLBMs are in existence, with the number of 'usable' weapons varying over time.

While much of the information is classified, Russia is purported to possess 1,643 first line nuclear warheads capable of being delivered by missiles (525 missiles) The TOTAL Russian stockpile of nuclear weapons is believed to be between 8-10 thousand, including 3,000 that are pending disassembly.
Russia, however, American technology was/is much more advanced.
Russia is permitted slightly more by treaty because their missiles are less accurate.

Russia and the United States were "Cold War" enemies. Soviet Russia supplied nuclear missiles to Cuba. Cuba is only 90 miles from the coast of the United States. Russia's reasons for supplying Cuba with nuclear capability... (You Decide)
Russia withdrew its nuclear missiles from Cuba and America, on the QT, removed outdated missiles from Turkey and did not replace them with new ones. The misnamed Red Phone was installed in the White House and the Kremlin to diffuse any future nuclear escalation.
Although a Nuclear war between the US and Russia is always possible it will most likely never happen. The US and Russia are the only two nations that have a Launch on warning system which is an alert to send interceptor missiles to destroy the incoming attack.
Yes, russia is the most expected to launch a nuclear attack on America, so America have nuclear missiles aimed at russia, so it can fight back. Defensive wise, i think there are some nuclear bunkers in the desert and important places like the whitehouse. So the answer to your question is yes.
The Cuban Missile Crisis. The Soviet Union was putting missiles on Cuba, with nuclear warheads. The USA found out and put a naval blockade around Cuba. For a few days, the threat of nuclear WW III between the USA and Russia looked like it might be a real possibility. The Russian ships sailed back to Russia. The Russians took their missiles out of Cuba, and the USA took their missiles out of Turkey.
