the problem for Trump is that when Nixon took the USA from a gold standard currency to an oil standard currency through the deal with OPEC where all oil transactions would happen with dollars which would prop up the dollar's value ... as the world is moving away from oil that affects the valuation of the dollar.
so Trump is trying to reverse course by destroying evidence of oil extraction and manufacturing being bad, and thus Trump thinks he will save the US dollar from its eminent collapse.
Just like how Bush toppled Saddam Hussein's government for offering to sell Iraqi oil for Euro's instead of dollars.
Just FYI
