PREFACE
FOLLOWING	 THE	 DISCOVERY	 of	 nuclear	 fission	 in	 1939,	 several	 nations	 began
programs	 to	 develop	 the	 ultimate	 weapon.	 Scientists	 in	 the	 United	 States,
including	many	who	had	studied	in	Germany	or	had	recently	escaped	from	the
German	campaign	of	conquest,	were	concerned	that	the	eminent	scientists	who
remained,	 including	 Werner	 Heisenberg,	 might	 be	 able	 to	 produce	 a	 nuclear
weapon	for	Adolf	Hitler’s	use.	The	United	States	tried	to	find	out	whether	those
fears	 had	 a	 sound	 basis.	 In	 addition	 to	 relying	 on	 traditional	 intelligence
methods,	 the	 Americans	 explored	 ways	 in	 which	 the	 signatures	 of	 nuclear
activity	could	be	detected.
In	1944,	scientists	deployed	with	the	invading	Allied	armies	discovered	that
the	Germans	had	made	little	progress	toward	an	atomic	bomb.	But	the	relief	felt
from	that	discovery	would	be	replaced	in	a	few	years	by	fear	of	what	the	Soviet
Union	might	accomplish	in	the	nuclear	field.	America’s	work	on	monitoring
German	progress	toward	the	ultimate	weapon	provided	a	foundation	for	the	far
more	extensive	and	long-lasting	intelligence	effort	to	uncover	Soviet	nuclear
secrets.
The	Soviet	Union	was	not	the	only	nation	whose	nuclear	activities	were	of
concern	to	the	United	States	in	the	next	decades.	Other	hostile	nations	seeking	to
become	 nuclear	 powers—most	 prominently	 the	 People’s	 Republic	 of	 China,
particularly	 given	 the	 loose	 talk	 about	 nuclear	 war	 that	 came	 from	 Chinese
leaders—also	 worried	 American	 presidents.	 At	 least	 one	 president	 seriously
considered	a	preemptive	strike	to	prevent	China	from	developing	the	bomb.
That	friendly	nations	might	try	to	join	the	nuclear	club	was	another	mounting
concern.	In	the	1960s	and	1970s,	U.S.	presidents	tried	their	best	to	discourage
Israel,	Taiwan,	South	Africa,	and	India	from	building	a	nuclear	arsenal—fearful
that	every	time	a	new	nation	joined	the	nuclear	club,	more	nonnuclear	nations
would	see	it	as	a	means	to	improve	their	status	in	the	world.	The	United	States
feared	that	nuclear	acquisition	would	prompt	regional	arms	races	and	ultimately
increase	the	risk	of	nuclear	war,	especially	in	the	Middle	East	and	on	the	South
Asian	continent.	More	recently,	the	nations	seeking	to	join	the	nuclear	club—
Saddam’s	Iraq,	Islamic	Iran,	and	North	Korea—would	be	at	the	very	top	of	any
list	of	nations	that	the	United	States	would	want	to	deny	membership	in	the
nuclear	club.
For	over	five	decades	the	United	States	has	devoted	considerable	resources	to
monitoring	 the	 quests	 by	 friends	 and	 foes	 to	 acquire	 nuclear	 weapons	 and
improve	their	nuclear	capabilities.	The	efforts	to	collect	and	analyze	intelligence
on	foreign	nuclear	weapons	programs	have	continued	to	involve	both	traditional
methods	such	as	human	intelligence,	aerial	reconnaissance,	and	communications
intelligence,	and	newer	ones	such	as	the	detection	of	the	signatures	of	nuclear
detonations	and	of	the	production	of	fissile	material.
The	 collected	 data	 has	 had	 many	 uses:	 keeping	 policymakers	 informed	 of
foreign	 nuclear	 activities,	 determining	 and	 estimating	 the	 nuclear	 warfare
capabilities	 of	 other	 nations,	 planning	 military	 operations	 to	 disrupt	 nuclear
activities,	 supporting	 diplomatic	 initiatives	 to	 forestall	 nuclear	 weapons
development,	assisting	inspectors	from	the	International	Atomic	Energy	Agency,
and	monitoring	compliance	with	a	number	of	arms	control	treaties.	The	latter
include	the	1963	Treaty	Banning	Nuclear	Weapons	Tests	in	the	Atmosphere,	in
Outer	Space,	and	Under	Water;	the	1968	Treaty	on	the	Non-Proliferation	of
Nuclear	Weapons;	the	1974	Treaty	on	the	Limitation	of	Underground	Nuclear
Weapon	Tests	(limiting	tests	to	yields	of	no	more	than	150	kilotons);	and	the
Comprehensive	Nuclear	Test	Ban	Treaty	that	prohibits	all	nuclear	testing.
Spying	 on	 the	 Bomb	 traces	 the	 evolution	 of	 the	 U.S.	 nuclear	 intelligence
effort,	its	successes	and	failures,	from	its	origins	in	the	early	days	of	World	War
II	to	the	first	years	of	the	twenty-first	century.	There	is	no	simple	explanation	for
success	 or	 failure	 in	 these	 endeavors.	 Given	 the	 different	 periods,	 different
individuals,	varying	targets,	and	different	technologies	available	for	collecting
intelligence,	that	should	not	be	surprising.
The	book’s	focus	is	largely	on	the	early	nuclear	programs	of	about	fifteen
nations,	and	the	U.S.	effort	to	determine	if	they	were	trying	to	acquire	nuclear
weapons,	 how	 far	 they	 had	 gotten,	 and	 their	 attempts	 to	 improve	 those
capabilities.	Thus,	the	core	of	the	book	examines	the	work	of	the	CIA	and	other
intelligence	agencies	in	identifying	and	providing	the	details	about	those	nuclear
programs,	as	well	as	the	agencies’	efforts	to	monitor	and	evaluate	nuclear	testing
—rather	than	their	efforts	to	gather	information	on	nuclear	arsenals	or	during
nuclear	crises.
