Buchanan: Romney as Taft

Is this an analogy too far?

While front-runner Mitt Romney said he would listen to the generals about when it is safe to get out of Afghanistan, he spoke out against any more wars to win independence for nations not vital to the United States. This is straight out of the Robert Taft tradition that America does not fight other countries’ wars or pay other countries’ bills.

But "not vital" is an escape clause, isn't it?
