The business dealings in Hunter Biden’s laptop were several foreign oil and gas deals, such as buying stakes in PEMEX, Mexico’s state producer, and Russia’s state oil company. If he was able to shut down US oil, those investments would be more valuable.
Obama/Biden shut down US coal to benefit China. They were perfectly happy to attempt the same with US oil and gas.
The only difference is that Joe did it for money and Obama did it for ideology. He hated the US, thought we needed to be taken down a peg, and promoted our enemies and their interests (particularly those of China and Iran).
