Because the anti-war American left is just that...anti-American and much more closely aligned with our enemies than with our own traditional national interests or underlying priniciples. It’s as straight forward as that.
I read the comments section on the UK Independents article on the war. It's a lefty publication and it was full of "Good for the Russians." "Nice to see friends of Bush get poked in the eye". "It's all Bush's fault" and "It's good to see Russia do this, they need to counter-balance the REAL Evil Empire".
I haven't been over to Dummieland, but I'm sure it's the same nonsense.
This reminds me that while we can feel for the Georgians we have lots of problems of our own that are more pressing including a huge subversive fifth column of self-hating leftists in our midst.
There is also an obvious corrallary between the Russian excuses for this war, and the future excuses that the Aztlan groups will make for sucession of the heavily Latino parts of the USA.
