You've probably already seen Isao Hashimoto's 2003 multimedia/video artwork 1945-1998, but to sustain my Anglophilic creds, I'll bloviate on it in light of the UK nuclear tests it shows. Hashimoto's work's gained global recognition recently via YouTube on which it's had more than 3.3 million views. The only similarly impactul time-elapse global map I've seen is the one in the American Museum of Natural History (AMNH) concerning human population growth, but Hashimoto's is an artistic work, and as a carefully crafted aesthetic project it may be informative and conscious-raising, yes, but it is also visually mesmerizing, the colors, pacing, typography, electronic tones, and other elements (note how Japan is at the geographic heart of the work) all being considered and working to create a whole that's greater than the sum of its parts.
Notice that Britain's tests include some that occured in the American West. As the U.S.A.'s closest Cold War ally, Britain had access to some of our testing grounds.
But Britain seems through to nuclear testing, and perhaps nuclear deterent in general. In Britain right now there's debate about the UK Trident missile program relative to both regarding both the program's expense and the fact that if Scotland votes to leave the UK in September 2014 the use of the naval bases where the UK's submarine-based nuclear arsenals are harbored, which are mostly in Scotland, will have to be sorted out.
The Scottish complication is the more immediate one. Scotland joined the union voluntarily as an arrangement finalized in 1707 that was in part a sort of economic bailout by England, and there's no mandate through UK constitutional law that the union must exist in perpetuity. If Scotland becomes independent they would, according to the Scottish National Party (SNP) that's driving the independence movement, join the Commonwealth and keep the Queen as head of state. To me is seems the SNP are desperate for the referendum to pass, and they'll likely succeed in lowering the Scottish Referendum voting age to 16. I imagine there'll be lots of showings of Braveheart in Scotland in the next few months, and I suspect the Scottish will vote for independence by a slim majority.
What will happen then? Relative to the Royal Navy bases, it's not clear. In terms of Scotland in general, they'll likely try to follow a Scandinavian model with a sovereign wealth fund supplied by their off-shore oil claims. I suspect they'd not be in NATO, which is all the more reason the rest of Britain will want to retain the entirety of the nuclear arsenal.
