You seem to imply that Charles de Gaulle and his policy of converting dollars to gold caused the collapse of the Bretton Woods system. That was a myopic view. The whole Bretton Woods system was doomed from the beginning due to design defects.
The system was conceived with the primary goal of maintaining balance of payments equilibrium for all countries at the expense of economic growth and liquidity. It had become clear that if a country wanted its currency to be the world reserve currency it had to run a balance of payment deficit. And the United States clearly wanted its dollar to be the reserve currency unbridled by any balance of payment constraints.
If the United States had balance of payment surpluses as it had in the early years, the system lost liquidity (other countries wanted to buy U.S. exports but had neither gold nor dollars to do so), reducing the surplus. And if the United States had balance of payment deficits, well, gold would flow out of the United States, and the United States could not meaningfully increase public debt or spending.
