My dear penguins, we stand upon a great threshold! It's alright to be scared; most of you won't be coming back.
It's difficult to come up with a word that succinctly describes this silly bit of wingnut dead-ender logic. The one word that comes immediately to mind is "inane." I'm sure you could come up with a better descriptor.
To try and wrap your brain about where he's coming from you really should read the Boston Globe piece he links that he's so unsuccessfully trying to riff on. He's basically taken the original opinion piece by Joan Vennochi and inserted Harry Truman's name wherever George Bush appeared in the original. Hey, nobody ever accused conservatives of originality.
This ongoing pattern of attempting to conflate the war in Iraq with WW 2 has quickly moved from cute but wrong-headed to downright sad. It's one thing to formulate an analogy only to have it collapse under the weight of it's own internal logic. It's quite another thing entirely to stick with that analogy after said collapse.
It should be more than obvious to anyone with even a smathering of understanding of world history that the current conflict against fundamentalist extremists is nowhere near the scale, nor poses nowhere near the threat, as the conflict against global tyranny that was the Second World War. Our enemy has no standing army. No navy. No air force. All they have is anger and intent. Hardly much of a threat to the world's last superpower, particularly if it remains vigilant and aware.
But what really elevates such screeds to the realm of pathetic is invariably the author won't be typing out their global call to arms from a tent in Baghdad or an aircraft carrier off the Gulf, but from the safety of a keyboard a half a world away. In the case of the above article the author, DJ Drummond, is a grad student. He is not fighting in this war.
I'm sure Drummond would have some excuse or another as to why he's not in uniform patrolling the streets of Baghdad but the long and the short of it is that, whatever his excuse, his argument in support of the war comes across thusly:
We are fighting WW III in Iraq. Our enemies threaten our lives, our faith, our very way of life. But don't ask me to fight because I have better things to do like finish college.
