While I have no doubt US Forces would prevail eventually, I also have no doubt that Russia's best...not the export stuff...will have more than a few surprises for us.
They also maintain the ability to strike and do tremendous damage to US/NATO forces and airfields, depots etc.
A dozen Blackjack bombers can wreak havoc all on their own, but when combined with the rest of the Russian Air Force they will definitely get some targets.
The American public is not used to taking losses and Congress is even worse.
The US public does not care about Estonia and certainly will not tolerate a sustained conflict over it.
The only question is if Estonia is sympathetic to Russia, and since they aren’t in the majority, it makes no sense for Putin to go against a well-funded guerilla campaign.
No one really prevails if we have a nuclear war. The question is why would Russia commit national suicide over a tiny town in Estonia?

I don't think you comprehend what is at stake here. The reason that NATO and our policy of deterrence and containment worked for 45 years and caused the collapse of the Soviet Union is that the Soviets believed we were credible on the use of force. Mutual Assured Destruction (MAD) has no winners and the losses will be devastating for everyone.
