Well, U.S. produces a lot more oil than it consumes and can supply most of Europe's net imports this way. Counting in Canada, in a pinch, North America and EU put together, can make do with just the (fossil fuel) energy supplies of their own.

So what you say was the case 20 years ago but no longer. Energy supply-wise, U.S. does not care about Middle East at all, and Western world overall, only somewhat cares, but it's not a major concern, not like it was in 1970s let alone not like it was in 2000s.
