Good work in New York.  Intelligence is still trying to figure out how a small-time, regional group like the Islamic Vanguard managed to launch an operation in the States.  It's pretty obvious they had help - we just don't know from where.

The people holding the tanker are rabid anti-nuclear types.  They won't hesitate to blow the ship if they suspect you're on board.  If that happens, the resulting oil slick will foul the plumbing of at least three nearby seawater-cooled reactors and bring down half of Japan's power grid.  You'll have to hit them hard and fast.
