"We freed them from a dictator and set free elections. "
Tough to appreciate your freedom when you are dead.
I don't for a second believe that bush went into the war for oil. I think he went in with a noble goal of giving those people freedom.
I think he is fundamentally wrong in that doing so imposes his value system onto a people not ready for it. In that perspective, he is no different from Taliban, in their desires to impose their value systems onto others forcefully.
There is some truth to the notion that the US is the biggest risk to peace. Just look at the number of wars over the last 100 years, especially since the downfall of the USSR.
Because of that, I'm the biggest supporter of foreign policy principles of Obama, Trump and Paul. They all called for minimum use of military forces overseas, with a focus on homeland defense.
Unfortunately we have a Republican congress that doesn't understand why you have a strong military, a defense secretary who doesn't appreciate us strategic interests, and some generals whose more interested in fighting wars than fighting off us enemies.
In the end, a strong military can lead the US to its own demise, aka USSR replay.
