You mustn't forget the incursions, however slight, from Mexico in the early Teens. ;)

Clearly that's why the US had to be drug into each of the major wars in the last century. Or why so many Americans favor of withdrawing our forces from Europe and most of Asia. Regardless, the Iraq war can't be solely about oil, can it? I mean, think. If all anyone wanted was Iraqi oil, they could get it by simply removing UN sanctions. What about the fact that the oil would go to France or Russia instead of the US? Who cares? Oil is "fungible". Every barrel of oil either nation bought from Iraq would be a barrel the didn't buy from the Saudis or Kuwait or Nicargua or Venesuela. More for us either way. Why bother with war when you could get the oil with a stroke of a pen?
