how can we produce a powerfull nuclear bomb that can destroy a whole country?

They already have it! It is called a Grid Square MRE Bomb! It is freaking awesome! Ithink there is actual footage of it on the internet!

A nuclear bomb is a weapon which derives its destructive force from nuclear reactions of fission or fusion. As a result, even a nuclear bomb with a relatively small yield is significantly more powerful than the largest conventional explosives, and a single bomb is capable of destroying an entire city.

It would take a lot more energy than is generated in one fusion bomb.  Watch the movie 2010: The Year We Make Contact.

In a 2-megaton explosion over a fairly large city, buildings would be vaporized, people reduced to atoms and shadows, outlying structures blown down like matchsticks and raging fires ignited. And if the bomb were exploded on the ground, an enormous crater, like those that can be seen through a telescope on the surface of the Moon, would be all that remained where midtown once had been. \n\nThere are now more than 50,000 nuclear weapons, more than 13,000 megatons of yield, deployed in the arsenals of the United States and the Soviet Union -- enough to obliterate a million Hiroshimas. \n\nBut there are fewer than 3000 cities on the Earth with populations of 100,000 or more. You cannot find anything like a million Hiroshimas to obliterate. Prime military and industrial targets that are far from cities are comparatively rare. Thus, there are vastly more nuclear weapons than are needed for any plausible deterrence of a potential adversary.

It’s actually not that easy and I disagree that a student can make a nuclear bomb, dirty bomb, maybe, nuclear bomb, no. There is an isotope of uranium that is required. An isotope is an element with the same number of protons but a different number of neutrons. Common uranium is known as U238. Uranium used for making bombs is the rare U235. Once enough U235 is gathered, it must go through an enrichment process. Various equipment and technology is needed. Yes, the United States has been able to this for more than 60 years, but the technology is heavily guarded by the civilized world. Iran has had to start from the beginning to develop the technology which is not trivial.

Completely dependent on the megaton yield and geography, e.g., mountains reflecting the blast wave or shielding from the heat wave.\n\nSettle for Washington DC. Virtually no one in an area of about 40-65 square miles would survive.\n\nTo visualize the destructiveness of a nuclear bomb, imagine a powerful strategic nuclear weapon detonated above the Pentagon, a short distance from the center of Washington, D.C.  Imagine it is a "near-surface" burst--about 1,500 feet above the ground--which is how a military planner might choose to wreak blast damage on a massive structure like the Pentagon. Let us say that it is an ordinary, clear day with visibility at 10 miles, and that the weapon's explosive power is 300 kilotons--the approximate yield of most modern strategic nuclear weapons. This would be far more destructive than the 15-kiloton bomb detonated at Hiroshima or the 21-kiloton bomb detonated at Nagasaki. \n\nThe detonation of a 300-kiloton nuclear bomb would release an extraordinary amount of energy in an instant--about 300 trillion calories within about a millionth of a second. More than 95 percent of the energy initially released would be in the form of intense light. This light would be absorbed by the air around the weapon, superheating the air to very high temperatures and creating a ball of intense heat--a fireball. \n\nBecause this fireball would be so hot, it would expand rapidly. Almost all of the air that originally occupied the volume within and around the fireball would be compressed into a thin shell of superheated, glowing, high-pressure gas. This shell of gas would compress the surrounding air, forming a steeply fronted, luminous shockwave of enormous extent and power--the blast wave. \n\nBy the time the fireball approached its maximum size, it would be more than a mile in diameter. It would very briefly produce temperatures at its center of more than 200 million degrees Fahrenheit (about 100 million degrees Celsius)--about four to five times the temperature at the center of the sun.\n\nThis enormous release of light and heat would create an environment of almost unimaginable lethality. Vast amounts of thermal energy would ignite extensive fires over urban and suburban areas. In addition, the blast wave and high-speed winds would crush many structures and tear them apart. The blast wave would also boost the incidence and rate of fire-spread by exposing ignitable surfaces, releasing flammable materials, and dispersing burning materials. \n\nWithin minutes of a detonation, fire would be everywhere. Numerous fires and firebrands--burning materials that set more fires--would coalesce into a mass fire. (Scientists prefer this term to "firestorm," but I will use them interchangeably here.) This fire would engulf tens of square miles and begin to heat enormous volumes of air that would rise, while cool air from the fire's periphery would be pulled in. Within tens of minutes after the detonation, the pumping action from rising hot air would generate superheated ground winds of hurricane force, further intensifying the fire.\n\nVirtually no one in an area of about 40-65 square miles would survive.

Pretty slim,  in future global war will involve nukes.  And that will go really fast.

How can the world eliminate nukes all together?\n\nThis probably won't be solved, but all sides would like to be able to do this, and I would think they would not call others names on this topic

Theres no system, but lots of ideas.  And none of the reasonable sane ideas include drilling a hole and dropping a nuclear bomb into the asteroid.  Damn you bruce willis, damn you.\n\nConsidering it only takes a meteor of about 50m to produce an explosion the size of a decent nuclear bomb, its very scary, look up tunguska 1908 impact.

All the weapons that have ever existed on Earth couldn't do more than split Mars into a couple chunks, which would just gravitate back together. You would need to literally pulverize the planet, and none of the weapons that we can make are even close to powerful enough to do that.

A nuclear weapon is a weapon which derives its destructive force from nuclear reactions of either nuclear fission or the more powerful fusion. As a result, even a nuclear weapon with a relatively small yield is significantly more powerful than the largest conventional explosives... so practically it is.

If they are stupid enough to fire a nuke I think all nations with nukes should respond in kind. A few dozen big mushroom clouds coming from all the major powers would have a startling effect on all the countries who want to have a nuke.  Imagine it. One nuke from every country that has the capability to hit Iran. That would be like a huge "WHO IS NEXT" sign for the world to see.

There is a fine line between nuclear energy and nuclear WEAPONS.  Energy will benefit everyone greatly until a meltdown of course.  However researching nuclear energy and experimenting with it leads to some bad people having volitile materials which COULD BE used for a dirty bomb or full out nuclear weapon.  To answer the 2nd part of the question.. what do you THINK the US will do to stop them?  We will warn them once, ask the UN and get denied, then take matters into our own hands.  I vote move to Canada.

It depends what you mean.\n\nChances are it will become the next NUCLEAR power. \n\nMilitarily, no. Having a few A-bombs is not enough.\n\nTo have an economy that rivals that of the US or China. Not even close.

the ability to make or have nuclear weapons could destroy cities and kill millions of americans in one strike and lead to a global destruction if other countries launch after. poverty on the other hand is not an iminent threat to the US and does not have the ability to take down the us or the world overnight.

Yes,, actually we have a formula to build a Bomb that is a 500 megaton cobalt salted Nuclear weapon that if detonated could crack the core of this planet like a China plate in a shooting gallery, rip away half this plantes atmosphere, and knock this planet out of orbit around the sun,,pretty bad stuff huh?
