Anyone, and I repeat anyone, who has taken the time to view the readily available footage of the Allied siege of Berlin in 1945 would immediately conclude that even the hawks in the Pentagon wouldn't go there. I think the Russians alone lost 30,000 in the last 5 miles.
I also think those who are so ceratin the Saddam is so unpopular in his Shiah enclave in Baghdad are also sadly mistaken. He may be a monster but he's their monster.
