What if France maintained control over French Indochina?
If France maintained control of French Indochina, they would still be a power in Asia. With these troops they could put down the revolt in the Republic of Niger, so it wouldn't be independent in this timeline. Since France would share a border with Vietnam, they would be able to help the U.S. during the Vietnam War and make it a tie because no one can conquer Vietnam but the Vietnamese can't win a war on two fronts. With Vietnam being a draw, 1968 would be less awful for the Democrats so a Democrat would be in power when Watergate happened. This means Reagan would get elected earlier so the USSR collapses sooner. With the collapse of the USSR and France still having colonies, the US doesn't worry about Europe as much so the Argentinians are able to win the Falklands War, conquering Britain.
