Now that we get very little oil from there, we are no where near as reliant on them as we used to be. We are doing it more for the countries there and in western Europe, the latter of which still get most of their oil from there (less so than before, however).
A large part of the problem is that so many in both areas are "gun-shy", thus afraid that by confronting these groups that this will put them into the cross-hairs, and that certainly is true. But to not do so only invites more problems in the long run. Radical Islam shows no signs of going away-- quite the reverse.
Also, we in the west need to realize that groups like ISIS, al-Queda, Islamic Jihad, Hamas, Islamic Brotherhood, etc. have much in common even though they're not carbon-copies of each other. We need to understand this this is a global war that if we lose, we and a lot of other countries are going to be in a world of hurt, especially down the road. Remember that related elements can also be found in eastern Asia and northern Africa and, as we've seen, they can do a lot of damage.
When I see some posters blaming Israel for how their responding to Hamas, I want to pull my hair out because they apparently can't see the larger picture that Hamas is just one of the related threads these groups bring, and to just play footsies with them ain't going to solve the problem. This is war, and if those of us in the west don't understand this and get our acts together, there'll be hell to pay.
War's not pretty, and one shouldn't interpret that I'm saying that we and the Israelis don't have to use some restraint, but for all practical purposes this is WWIII, and we'd better win it or else, and the "or else" won't be pretty.
Ever read Clausewitz, btw?
