not trying to sound like a know-it all asshole, but the us and russia are the only countries with serious nuclear weapon systems, china india etc are regional powers, they devoloped missle systems for these regional conflicts...they tend to be mid ranged. as far as india/ pakistan and NK/SK are concerned they just need the ability to nuke each other... they arent concerned with us.
remember that a missle force like ours costs an absolute fortune to maintain let alone research and build. its a luxury that only an superpower can really afford. believe me, if there were an nuclear exchange, you would be worring about russian hardware raining down on us, not chinise NK indian or w/e.
keep in mind, the us'd gdp is still like 3x greater than that of china... the next closest. i dont think they are going to outspend the us in this hypothetical war.
alot of us hardware related to nuclear forces tend to be largely hardned against EMP warfare.theres alot of interesting modifications they made to bombers and such that make them very resistant. this protection largley conserves the mad concept. i think the us acually is of the position that an EMP attack would merit a nuclear retaliation,so whoever does it better do so anonamously.
i dont see any reason to worry about about any country or group of countries attacking the us outright anytime soon, its not to anyones advantage to do so anyway lol. china needs to sell us crap, and we need china to buy crap from. free markets have more potential to prevent war than any diplomatic envoy ever will.
Canada is not as venerable as you might think. Canada been a member of nato for decades. also Canada actually plays a pretty important role in the us's early warning systems too. we had/have dozens of radar installations looking out over the north pole searching for bombers etc. other than the us itself, you guys are probably the most protected by the so called nuclear umbrella.
