I would absolutely NOT want any of this to occur no matter who won or lost..
The best way to make sure it does not happen is for them to know that they cannot win against the USA.. Deterrence..
The leaders know, but most common people do not..
This is also the reason why the US doesn't get rid of Putin to install their own puppet and be done with it: They make sure you understand they can hurt back as well as you do.
Your fantasy commenting is not how real life works. The US does invest too much money in the military, and you better do well to justify it, because words don't make actions and people will get angry if the toys don't justify their cost. But the US is not mighty invincible, it can be hurt, that is why all departments have to work so hard to avoid or leave the military always as the last resort.
In a nuclear conflagration you just cannot stop ALL of them, that was the point of MAD, and its the reason everyone stopped from using nukes ever since (out of fear).
Now this EMP thing is nothing to write home about. Maybe its just some EMP mounted in a supersonic missile, maybe the idea is to launch those ahead to attempt jam the defenses before the ones with actual payload hit. The Russian (and Chinese?) deterrent works as follow: Enough numbers of supersonic missiles are still cheaper than, say an US carrier. And given enough numbers, some will pass. Only one needs to hit the carrier.
This is the anti us naval task force tactic they devised decades ago, and are continuing it. One keypoint is to make the Americans lose enough expensive toys so that people back home start questioning those responsible for the economic and human loses. And this is why you see so much emphasis in cruiser missile technology. No these have nothing to do with ICBMs, don't bring that because that is sub orbital stuff, not fly above the speed of sound close to the water surface or ground.
The Americans also have plenty of EMP things, but you should know this. The latest fashion is unmanned flying, but still probably more expensive than mundane supersonic missiles, yet cheaper than certain stealth planes and such.
No, the Russians are not attacking you so lower that pointless rhetoric (And Putin isn't going to get deterred by your comments in Bitcointalk). Military contenders for the USA? Realistically its just those two: Russia and China. Doesn't mean they have "more" firepower than you, but China certainly has more people and Russia more territory. Ask any military official and they rather engage some middle eastern country rather than those two; maybe not out of fear but out of cost, and human lives which tend to push the politicians against the wall and force their hands faster than the actual military opposition which will also play the attrition card, and lengthen the conflict like the ex-Yugoslavia conflict.
Rather than issuing threats no one here cares about (Seriously you are scaring no one with those "mighty" words), study what this is about and inquire in your own readiness and counter measures. That's what the actual professionals do anyway, solutions to problems.
Don't justify mistakes, How is that people died by the Iran attacks but it was covered up? Do you even remember what happened in Libya with the US embassy? Not all is "don't show the cards to the opponent", bad things do happen in conflicts. Maybe the cover was to give time to diplomacy and intelligence. The conflict did not escalate after all...
