More like the Saudis are driving the price down partly in order to inflict damage on the Iranians, with whom they are engaged in something close to a cold war, but mostly to choke out the high cost producers in the US and make future investments in that sector look very risky. There is definitely a strong destabilizing effect on Russia, Iran, and Venezuela at the very least.
