The Oil Weapon

 In 1973 the Arab OPEC countries punished countries that had supported Israel in the Fourth Arab-Israeli War by imposing an oil embargo on them.

In October 1973, the Organization of Arab Petroleum Exporting Countries (OAPEC) announced that it was implementing a total oil embargo against the countries who had supported Israel at any point during the Fourth Arab–Israeli War, which began after Egypt and Syria launched a large-scale surprise attack in an ultimately unsuccessful attempt to recover the territories that they had lost to Israel during the Third Arab–Israeli War. In an effort that was led by Faisal of Saudi Arabia,^[2] the initial countries that OAPEC targeted were Canada, Japan, the Netherlands, the United Kingdom, and the United States. This list was later expanded to include Portugal, Rhodesia, and South Africa. In March 1974, OAPEC lifted the embargo,^[3] but the price of oil had risen by nearly 300%: from US$3 per barrel ($19/m³) to nearly US$12 per barrel ($75/m³) globally. 

One wonders why they haven't done anything to punish those countries supporting Israel's nazi-like genocide of the people of Gaza.  Obviously, there's the possibility that the rulers of Saudi Arabia, Jordan and the Gulf monarchies are corrupt, bought-off autocrats who don't care about the Palestinians. But the other day I thought it might be possible that they don't want to hurt BRICs countries like Brazil, India and, most importantly, China.

Just some idle speculation on my part.
