Dude, Where's my nuke?

From the WSJ's Morning Brief:

The Defense Department mistakenly shipped secret fuses for Minuteman intercontinental ballistic missiles to Taiwan more than 18 months ago and did not learn that the items were missing until late last week, Pentagon officials acknowledged yesterday, deepening concerns about the security of the U.S. nuclear arsenal six months after the Air Force lost track of six nuclear warheads for 36 hours when they were inadvertently flown on a B-52 bomber between bases in North Dakota and Louisiana. Defense Secretary Robert Gates learned of the erroneous shipment on Friday and informed President Bush, but officials waited until yesterday -- after Saturday's elections in Taiwan -- to disclose the incident.

Why didn't Taiwan let us know?
