Well, ignoring the snark for a moment :), I would say that anyone has the right to protect themselves, which also includes oil companies.  That said I don't think that NATO forces are going all over the world trying to protect oil facilities or commercial property in general, that is not possible and not wanted.  Still, the need to prepare for and be ready for terrorist attacks in the future is, in my opinion, a necessity considering the vulnerability of most NATO members' states when it comes to, amongst other things, energy supplies.  Al-Qeada has demonstrated its willingness to attack such installations and infrastructures, where ever they might be, previously and have stated that this is going to be part of their strategy for the future.
