That's where you and I differ Goldy. I believe Obama achieved world peace in his 8 years because he didn't make idle threats. He didn't invade other countries. He achieved things like the Paris Climate change agreement for the good of all the people of the world together, irrespective of Borders. He saw the full picture. Trump will reverse all that in an instant.
Each country in Europe is retaining it's own culture as far as I can see. I would rather go on a journey from Dublin to Istanbul and enjoy the different languages, the different food, the all the different cultures and landscapes than a journey from LA via Taxas and Oklahoma to New York where nothing changes throughout the journey. Trump believes in dividing his own nation and upsetting his neighbours. I can guarantee you one thing, the world today will be a far better, more peaceful place overall than the world the day Trump walks out of office. America will be far more divided in 4 years time than it is today. Not too sure why you say Michelle Obama looks down her nose at the Emerald Isle. I always got the opposite impression.
