U.S. allies unite to block Obama's nuclear 'legacy'

President Obama’s last-minute drive for a foreign-policy legacy is making U.S. allies nervous about their own security. Several allied governments have lobbied the administration not to change U.S. nuclear-weapons policy by promising never to be the first to use them in a conflict.

The governments of Japan, South Korea, France and Britain have all privately communicated their concerns about a potential declaration by President Obama of a “no first use” nuclear-weapons policy for the United States. U.S. allies have various reasons for objecting to what would be a landmark change in America’s nuclear posture, but they are all against it, according to U.S. officials, foreign diplomats and nuclear experts.
