I would think that Bush Sr. has been rather upset by Dubya's policies since 9/11. After all it was 41, who in Desert Storm, stopped the troops from invading Iraq (and thereby invoking the wrath of the neocons). His reasons why we didn't invade, which he explained in his book, have all come to pass. He was a farsighted president who thought of the good of America not just the consevative agenda and I feel sure he's horrified at the position that Dubya has gotten us into.

PS It does seem that Bush was seduced by Dark Forces.
