Crockerland is adherent to the Biological Weapons Convention and does not possess a Bioweapon stockpile.
Crockerland maintained an arsenal of Phosgene weaponry in the early 1920s, the cruelty of these weapons lead to a plan to disable them all by 1940, but the collaborative conquests by Nazi Germany and the USSR aimed at northern Europe lead this plan to be abandoned. Crockerland is a party to the Chemical Weapons Convention and completely destroyed or otherwise rendered inoperable 100% of it's chemical weapons as of 2011 in accordance with the terms of the convention.
Crockerland has historically possessed nuclear weapons and conducted nuclear weapons tests, it is capable of producing them again and is "one screwdriver's turn" from being a nuclear weapons state, but has never stockpiled these weapons for purposes of war. Crockerland has the sea, air, and land means to become a nuclear triad, and is not a signatory to the Non-Proliferation Treaty or Partial Test Ban Treaty.
Agartha Test, 1977
Following America's withdrawl from Vietnam and refusal to defend the Republic of Vietnam (South Vietnam) in 1975 under US president Gerald R. Ford, and the boycott by France and the UK against the government of Rhodesia, the government of Crockerland under president Ezekiel Hayes had reason to believe they would not be defended from foreign attack by nuclear powers.
With the government already delving into nuclear power as a result of the Arab embargo of 1973, Crockerland began work on a bomb in 1975. Crockerland's first bomb, a 16-kt yield atom bomb, was detonated in the desolate landscape of Grant's Land, the mining city of Agartha, Grant's Land, was the nearest location, and the test's namesake.
Crockerland did not produce any other functional bombs in this program, besides the one used in Grant's Land, but was nonetheless often suspected of having done so.
Roald Corridor Tests, 1985
Crockerland produced two nuclear bombs for use in offshore tests in the 1980s. Instead of Uranium or Plutonium, these bombs used Neptunium 237 and Americium 241, the purpose of the tests was to determine the feasibility of these elements as bomb components in order to regulate their industrial use and waste storage.
Both of these tests were conducted in international waters of the northern Pacific Ocean. Two Neptunium bombs were produced, one of which was disassembled, while the only Americium bomb produced was detonated.
Rhind Test, 1999
Under president Edward Rhind, who the test is often named after, a second-generation thermonuclear weapon was designed and tested in the north pacific in 1999 using an ICBM delivery system. The bomb used well exceeded 1,000 KT in yield, and was the last nuclear weapon produced by Crockerland.
The Green party, Libertarian Party, and Conservative Party were outraged by the test, and Rhind was voted out in 2000 in favor of Conservative Party candidate Robert Henson, largely as a result of the unpopularity of his unilateral test. The NLP regained popularity in the 2010s and the nuclear test is now largely viewed favorably due to increased North Korean aggression and the rise of Islamic terrorism.
