Update:
As North Korea Blusters, South Breaks Taboo With Nuclear Talk:
"two recent opinion polls show that two-thirds of South
Koreans support the idea posed by a small but growing
number of politicians and columnists — a reflection,
analysts say, of hardening attitudes since the Feb. 12
underground nuclear test, the North’s third such test
since 2006.
“The third nuclear test was for South Korea what the
Cuban missile crisis was for the U.S.,” said Han
Yong-sup, a professor of security policy at the Korea
National Defense University in Seoul. “It has made the
North Korean threat seem very close and very real.”"
"“Having a nuclear North Korea is like facing a person
holding a gun with just your bare hands,” said Mr. Kwon,
the engineer. South Koreans should have “our own
nuclear capabilities, in case the U.S. pulls out like it
did in Vietnam.”"
