Does a robust foreign policy have to mean multiple, interventionist wars?
I cite Thomas Jefferson, who dispatched the entire fleet to have "regime change" in Tripoli, WITHOUT A DECLARATION OF WAR but with only a joint resolution (which he then used to declare war, not only on Tripoli, but on all states aligned with Tripoli---can you say "with us or with the terrorists?")
Jefferson's war was highly effective. We had to go back one more time, under Jimmy Madison, but both were brief, to the point, resulted in "regime change," and pretty much that was it until the 1970s from that region.
Interventionist does not mean permanent, nor does it mean costly. In the entire Tripolitan Wars, we lost, I think, two ships (one of which we burned ourselves) and sent a grand total of 8 Marines.
