Pangea if Pangea still existed, it is safe

Pangea was the name given to a supercontinent that assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.
How would the catastrophic events of the last 10 centuries, from World War 2 to Columbus’ expedition to the Americas, have turned out if the world had stayed as one continent? What would civilization be like if humans lived on Pangea?
Theoretically, if Pangea still existed, it is safe to assume that humans wouldn’t have as a result of disease, evolution .
However, it is one thing to see the continents reassembled into a solitary mass but quite another to see the US state of Florida edged in between the Guyanas and the Guineas; to witness Antarctica, Australia and the Indian subcontinent conspiratorially huddled together in the world’s most implausible trio; to see Newfoundland, on Canada’s east coast, function as the wedge that drives Morocco and Spain apart; or to discover Iran mercilessly chopped in three, fragments flung far across the Tethys Sea.
The result of Pangea is a planet where the most unlikely pairs become neighbours – Antarctica and Australia, Russia and North America, Africa and the United States. Every country is connected, which makes the idea of conflict a lot more difficult to comprehend.
Can you imagine what would have happened if the Nazis had attacked on the same continent rather than crossing the seas? Would Germany have won the war or would have Britain still conquered? Well, let me offer you a possible scenario. Island nations such as Britain have seen relatively less warfare than nations that directly border each other, and that is because it is easier to initiate conflict when you can get to your enemy’s front door on foot however if there was no requirement for the Germans to cross the seas, then there would be an urgent need for a standing army at all possible land borders in Britain.
When your country is surrounded by miles and miles of ocean, the need for a standing army goes down. This decreases the need for a big government so if every country was separated by at least six miles of ocean
