as with Hitler & Stalin
In the words of Hitler, "there is more that binds us to Communism than divides us".
Bush & bin laden are both driven by religious fervour, both think they are doing the right thing in the face of all evidence to the contrary, both will continue steering their ships full speed in the same direction regardless of the huge iceberg looming dead ahead.
Neither takes any apparent notice of world opinion, or indeed any point of view which differs from their own. The only difference really is that Bin laden is prepared to go much further, commit worse atrocities and war crimes.
