This whole thing comes down to the general opinion of the American people and who controls their collective opinion.
Wu Cheng'en said in the mid 1500s, "If you think you can or can't, you are right."
If we think we will lose in Iraq then we will.
If we think it is winnable, it is.
I personally think it is winnable, but it may take as long or longer than the cold war did.
Win or lose... I get tired of hearing about winning the war...FYI..we won the war in Iraq in a couple of weeks...the war we are now involved in is worldwide... In terms of numbers of our soldiers...far more are killed in our inner cities by gang bangers each day than in Iraq.
Also....if we want to preserve our way of life here in America....we better win this war.
