I don't think that this question should ever be answered in great detail, since so crazy person out there is probably going to then blast this world to smithereens. I'm sure the amount of nuclear bombs could be calculated, but then, who on earth would want to know that? We'll all be dead and that is that. Thankyou.
As stated, the question is overly obvious; the world can be destroyed only once because once it is destroyed, there is nothing left to be destroyed, right? How many times could the same ceramic dish be shattered? More than once, but only if you are willing to glue it together again, and if the whole world were to be shattered, there would be no one left to glue it together again (unless you are expecting aliens from outer space to take an interest). However, you might have been thinking of the principle of overkill, that the nuclear arsenals of the world contain more weapons than would be needed to destroy the entire world. At a rough guess, the total inventory of nuclear weapons in the world is sufficient to destroy a dozen worlds at least (if we had a means of getting to other worlds, of course). But the Earth can be destroyed only once.
That would depend on yields. Also simply killing all humans would take much much less.
it takes about millions and millions of years to develope a nuclear power.

It is difficult to answer how many nuclear bombs it would take to destroy England due to the fact that there are a variety of different nukes. It would most likely take around a couple of dozen.

Lasers because if the laser hit the missile or the bomb it can take them out really fast.
No, the President of the United States does not have a "red button" of any sort, in the Oval Office or elsewhere. Nuclear Missiles cannot be deployed from a direct command from the President; his command must be confirmed by the Secretary of Defence before the military take action. Note that the Secretary of Defence cannot authorize the launch of Nuclear Missiles without the President first doing so. Nicknamed the "Football", a black briefcase is carried with the President at all times. The briefcase is believed to contain nuclear codes and various pieces of equipment that authorize the deployment of Nuclear Missiles wherever the President is in the world; it functions as a mobile hub in the strategic defense system of the United States.
A 13 day political military
The Cuban missile crisis was the closest flash point the world ever came to a nuclear war. It lasted only 13 days.Khrushchev gave order to withdraw the missiles from Cuba and Kennedy, secretly ordered to take the missiles located in Turkey, back to the USA.
A historian might describe the tactics the United States might have used to physically destroy the missiles in Cuba.
Take a rocket and put a nuclear warhead/bomb in its payload, instead of a satellite or humans. This produces a nuclear ICBM.Shorter range rockets or unmanned jets aircraft called cruise missiles can also be used.
Missiles are disassembled by special experts who know how to handle the nuclear devices and to properly dispose of them. It costs about a million dollars to take them apart and they can take as long as two weeks. There is a show on Discovery com that shows these experts taking them apart. The US government has had well over a thousand taken apart. It is classified where the nuclear materials are stored.
It may take a thousand of tons on TNT to pack a nuclear bomb. But to destroy the earth, it may take billions to trillions tons of TNT plus a nuclear igniter to blow the earth to bits of dust.
Surprisingly few ! The 'super powers' have enough nuclear weapons between them - to destroy humanity many times over !
