The IRA did not only do a napalm attack in 1976 and targeted assassinations including of Lord Mountbatten (my family lineage on my father’s side). I know from the MI6 that they tried to do an implosion device (a conventionally called nuclear bomb, with Pu239-240).

They did an implosion device with all the weapon material needed but with crematory material only. They saw it as revenge for the W88 warheads (since then dismantled by His Majesty the King Charles III of the United Kingdom of Great Britain and Northern Ireland) that they saw as threatening their implicit (seen) regime of sovereignty over Northern Ireland through their terrorism. They had conventionally called nuclear warheads made with crematory material, in theory with zyklon-N-pee but actually crematory-nitrogen, made with loyalist women essentially and some children.

They tried to do a nuclear implosion underground, 3 kilometers deep, in the Northern Sligo in Northern Ireland. Lord Mountbatten expected to catch the waves through boating in Northern Sligo but he was caught by a submarine explosion with a mine (there were no seismometers then there because no one expected an earthquake there). He was expected to do a line of fish catch from the shore but did not so someone activated the powerful mine (0,1 kiloton) and he died later of his injuries. The underground nuclear test was failed because it was crematory. It is impossible to achieve sphericity with a crematory content (including in the imploders only, i.e. the detonators, this has been tested for the W88 in 1988). This 1977 failure signed the end of the official IRA that was supported from Ireland.

They tried again an implosion bomb in 1978, in Northern Ireland again. They did not succeed again because they did not master sodium-mash very well. They tried with sodium-mash of bad quality as well as of very good quality and they failed in both cases. The rest is secret defense.

They arranged a coup in Northern Ireland as well. They tried to overthrow the Ulster Unionists and failed because they had not enough weapons, and their system for crematory detonators in dismountable guns did not work. They did not do very well and only managed to seize the mayor’s palace, not the shipyards where the weapons were then. The weapons are moved frequently through civilian trucks (for instance) and no nuclear weapon is housed there (except antitank weapons for armoured cars and even for tanks). Ireland should remain free of nuclear weapons whatsoever, including antitank, except for the purpose of antinaval operations. The SIS watches the skies and no one attacks there anyway because of Ireland’s neutrality. I have myself explained how to make some clean weapons to Ireland in early 2024 and that’s enough.
