In the early 1940's some of the greatest scientific minds of all time gathered in Los Alamos, NM for an "R&D" project, infamously dubbed the 'Manhattan Project', that ultimately changed the course of human history forever.
Just a few years later, on July 16th, 1945, that team of scientists detonated the world's first nuclear weapon, code-named "Trinity", in the desert just north of Alamogordo, NM. Less than one month later, the only two nuclear weapons to ever be used in combat were detonated over Hiroshima and Nagasaki resulting in over 100,000 immediate civilian and military deaths.
And while no nuclear weapons have been used in a combat situation since August 9, 1945, as revealed by the following animation, a staggering number of tests have been conducted all over the world and most of them in the deserts of the Southwestern United States.

And while nuclear tests are somewhat more rare now than they were during the height of the Cold War, there remains a devastating number of nuclear warheads deployed and ready for launch today...a fact we recently detailed in the post below entitled "15,000 Nuclear Weapons In The World - Mapping Who Has What":
So, how many nuclear weapons are there, and what exactly is happening right now? Let's launch into it.
WHO HAS ACCESS TO NUCLEAR WEAPONS?

As VisualCapitalist's map above demonstrates, the United States and Russia still maintain the world's largest stockpiles of nuclear weapons, holding 92% of the world's estimated 15,000 nuclear warheads.
While today's arsenals seem quite excessive, they are actually quite modest compared to historical totals such as those during the Cold War. In 1986, for example, there were actually 70,300 nuclear weapons globally - but luckily for us, the number of warheads has eased down over time as countries disarm more weapons.
Will this number of warheads continue to slide down as a result of increased international cooperation? The Brookings Institution has grouped the nine countries with nuclear arsenals into categories that identify prospective entrants to the global arms control regime:
Any advancement of multilateral arms control, such as a treaty limiting limiting nuclear weapons, would likely take place between these countries.
MAPPING NUCLEAR SITES WITHIN THE UNITED STATES
Thanks to various arms reduction agreements, thousands of nuclear warheads have been retired. That said, warheads are still stored in a number of sites around the continental United States. The map below also highlights laboratories and interstate shipping routes. (Yes, nuclear weapons are apparently shipped in big rigs.)
THE WILD CARD: NORTH KOREA
The Hermit Kingdom is a relatively minor player in the nuclear weapon ecosystem, but they have been capturing the world's attention. Under Kim Jong Un, North Korea has dramatically ramped up the frequency of missile tests, with 17 confirmed launches so far in 2017.
Here's a look at the country's arsenal of nuclear weapons, along with ranges of specific weapons.
More than a decade has passed since North Korea detonated its first nuclear weapon, and the country is now believed to be capable of intercontinental ballistic missile delivery. This, combined with aggressive rhetoric from North Korean leader, Kim Jong Un, has forced the Trump administration to take their threats more seriously.
That said, experts suggest that recent provocations aren't much different from previous periods of tension between the two countries, and that the risk of an actual conflict is overblown.
North Korea's comments are clearly deterrent in nature, and the Guam ‘threat' was exactly along those lines.

Either way, while the prospect of an all-out war is unlikely - the war of words between North Korea and the United States is likely destined to continue.
