Latest reports from spokespersons for war senators McCain and Graham indicate the chemical weapons allegations against Assad are being pushed to the rear in war preparations underway in the US.
Questions on the accuracy of the August 21 chemical weapons intelligence are no longer as important as wider considerations.
The "red line" problem, or credibility problem, has taken over the war case even if it was the rebels (not Assad) who used the chemical weapons.
National security and other interests require credibility as a basic, and if US intelligence on what happened August 21 is incorrect that is not the administration's fault.
The more serious problem is the redline credibility issue dating back to 2012 in which Mr. Obama has insisted use of chemical weapons by Mr. Assad is a redline which will bring a response.
This redline seems to have been crossed previously, and now again (or not). The crossed or not problem is currently seen as "dithering" with a corresponding urgency to act by doing something.
In fact, in a strange irony, even though this redline emerged from the US itself, it has indeed reversed. It has become a weapon circling back to strike the US.
According to the best military thinking, as with Mr. McCain and Mr. Kerry, defense of the US against this boomerang is to shoot it down with tomahawk missiles in Syria, and most likely boots on the ground too.
Moreover, it's been quite a while since America's most recent war, so a new one will bolster national security credibility in the future for more wars upcoming, a wise investment.
The problem is if the US does not strike big here to show the size of its muscle enemies will laugh and hold a celebration, plus stiffen their resolve.
However, there is a large BUT to consider for further perspective on this matter.
If war is ordered up anyway, despite current levels of opposition in the Congress and the American public, another credibility problem may emerge. It too could boomerang toward the President and the war supporters.
That is, the American people and the Congress could initiate impeachment proceedings additional to voting out war supporters from office in the midterm elections.
However, Senators McCain and Graham are entirely on board with Secretary Kerry in response that this is the lesser danger.
A spokesperson used an analogy to explain that "the proof is in the pudding."
That is, the pudding for the attack on Syria continues to cook, and the administration has full confidence the American public can soon be convinced the administration is correct.
The recipe includes rightness, righteous indignation, patriotism, repeating the words "doing the right thing", plus insisting that opposition to war is aiding and abetting the enemy.
True, a little salt in itself may be too strong, but added to the overall mix a tasty and satisfying meal is the most likely outcome from this new regional war in the middle east, about to begin.
