I think the final refusal of Turkey to allow a second front via thier country is the biggest news of the war so far.
While it is not dire, it definalty throws a major wrench in both the stratagy and tactics of the US operation.
CNN of course is barely mentioning the issue. But look at what happens.
1/3 of the US troops, the ones intended to push south from Turkey and secure the Kurdish area and those oil fields and then pressure Bagdad from the north are still in ships on the third day of the war and will not begin to disembark till probably 4 more days.
When they do disembark they will be as far from thier original objectives as is possible and still be in Iraq. The logistical support for them will have to pore through the same ports as the other units instead of coming through the turkish ports.
Taken in its total. This is a phenominal change forced on the US war effort by Turkey. How late in the war the US still tried to get Turkey to allow the troops passage shows how serios this change is. Now those units will be part of the second week of the war. Instead of the first hour.
The only way to trump this is if the Egyptians denied the US use of the Canal.
Anyway. I think the Turkish denial of access will be the everwhelming issue identified in the history books in the first few days of this war.
