Hitler never wanted to a war with Great Britain.
Perhaps but not for the reasons you have stated and the admiration bit is also over the top. You can acknowledge someone's successes and learn from their tactics but you would never ever admire anyone who you consider to be racially, mentally and culturally subservient to yourself. While Brits might have been considered a step above the Slavs, still you were not true Arian either, that honour was reserved for someone of the pure German blood only.
He admired the process by which little Britain controlled its huge empire by using 'locals' to do much of the administrative dirty work, a process Hitler was keen to emulate in the Nazi occupied territories.
He never planed on doing such thing. His plans for the East and its people are well documented by the historians. The very first days of the war had shown that the Nazi invader was devoid of any humanitarian feelings and had no respect for international conventions or rules for the conduct of war through which it had shown what was about to follow. Every day brought reports of atrocities being committed on the civilian population by the Wehrmacht in the territories they had overrun. The occupation authorities proved themselves as brutal and vicious, and devoid of any laws be it that of the local population or that of Germany itself but could have they done otherwise?, when they were just looking after the livestock, yet you make it sound like they would have govern these territories in Roman fashion. At least the Romans had respect for the local laws and traditions. Both the British and the Romens for the most part cared only about the profits from the conquered territories. Which was demonstrated by the British administration of India and other parts of the Empire, Nazis did not, as we all know they had an ideological element to their conquest which was even more important to their notion of the Great German Empire and a Thousand Year Reich.
But Britain foolishly went to war against Germany to honour its pledge to Poland. Some might argue this was Great Britains biggest mistake of 20th Century, apart from allowing the Poll Tax protestors bring down Thatcher's government :-)
This very much depends on your perspective. I would had argue otherwise but if you do admire the policy and the vision of the new world order under Nazi regime then you do have the point.
According to Zweites Buch (the follow up to Mein Kampf) a final struggle would take place between the United States and the combined forces of Greater Germany and the British Empire.
Who are you kidding, at this point Britain would have served its purpose, no longer needed by the Thousand Year Reich and would have been discarded as easily as one discards dirty pair of socks.
Both of you can praise the Nazi Germany and make a descent attempt of defending Hitler's policies as well as what his plans for alliance might have been or what if scenario, but deep down inside you both know the bitter truth and what the reality and consequences of such alliance might have been.
