Daddy Paul is Anti-War because he understands (rightly) wars are economic disasters. What he can't get through his thick head is that most of us don't favor killing Islamic lunatics for economic gain (or fun), but because killing them is the only alternative they will permit other than them killing us.
I do understand what you're saying.
And as mentioned -- FWIW, Rand Paul is a little more hawkish than his dad on these issues. Maybe not enough of a war-hawk to please some; but hardly enough of a peacenik to make the anti-war crowd happy, either.
Most importantly, though, he's rock-solid on Conservative domestic policy. As long as Obama is Commander-in-Chief of the troops, that may be about the best we can hope for.
