Theoretically, yes. Practically, no, nobody has ever built a single bomb of high enough yield to destroy an entire country in one shot; also any such bomb would waste most of its yield in simply blowing off the top of the atmosphere into space. It just isn't practical with a single bomb.
Yes, a fusion bomb (hydrogen bomb) would destroy New York City.
depends on yield an height/depth of burst.
Well if you don't know its a bomb and its actually called nuclear bomb, nuke is short for nuclear. It has the power to destroy a whole NATION. And to answer your other question it looks a missle. if don't know what a missle looks like, you can look up Missles and or nuclear bomb on Google images
the hydrogen bomb, is a nuclear bomb
A gigaton is 1000 megatons so it would be destroy an an area the size of Louisiana. But of course there is no such thing as a gigaton for bombs. IN FACT, there are already 1+ gigaton nuclear weapons. A 1 GT bomb would destroy an area the size of Texas, just with the expansive wave. A 90 GT bomb could change the planet trajectory.
no
No.
Yes, a fusion bomb (hydrogen bomb) would destroy New York City.
A neclear bomb could completly destroy a building :)
yes he has a nuclear bomb which is the most powerful bomb in the world and can destroy the whole of England. apparently there is only 1 in the world now

There are currently no nuclear weapons big enough that just one could destroy the US. It is possible that enough of them could pretty much destroy our way of life for decades to come.
Nobody has a bomb big enough to destroy the earth. The problem is, if one person detonates a nuke, there will be retaliation by other countries. This will lead to nuclear war, and ultimately the extinction of the human race and most other species of animals.
If you want to destroy a city and kill thousands of people, it is the quickest way of doing so.
To destroy large areas of land. Is one answer. The other is to blackmail other countries into submitting to you.
That would depend on yield and height/depth of burst.
