Oil "Siege" May Last Until Fall

The head of the U.S. Coast Guard has characterized the BP oil leak as a "siege" which will last for a significant part of the year:

Coast Guard Adm. Thad Allen said on Sunday that BP was succeeding in capturing more oil from its runaway well in the Gulf of Mexico, but cautioned that efforts to cap and clean up what’s already the largest oil spill in American history would stretch into the fall.

“We’re in the middle of a long-term campaign,” Allen, who’s coordinating the federal response, said CBS's “Face the Nation.” “This siege will go on for a long time. We have spread from South Central Louisiana over to Port Saint Joe, Fla. It won't end soon. We need to have our shoulder to the wheel, do everything we can. This is a very, very, very tough problem.”
