BP topples governments as a normal course of business. They are the 4th largest company in the world. This is a hiccup.
Worst case scenario, they toss their US operations to the wolves of lawsuit and focus on the rest of the world. That is, until we are crushed under the weight of higher gas prices and we quietly let them back in our market under a new name.
Remember their Texas City refinery blew up in 2005, killed 15, injured almost 200 more. They paid $1.6 billion to victims' families and a $50 million fine. Business as usual.
