The entire world knows that weak willed Obama has turned his back on US Allies to back the Islamic states and muslim terrorists.
Other nations, like France, Russia and China are flocking to fill the power vacuum he has left around the world.
Zero and/or his cronies gets a financial benefit from everything he does in office; beyond that he undermines the US at every turn, because he doesn’t work for us.
Iranian oil has been embargoed for years; naturally it still gets sold abroad to countries which don’t honor the embargo. Even though that *should* mean little impact on overall prices, the fact is, it helps to prop up the market price, as Iran sells by contract straight to various other states (India I think, China also) and if memory serves, Iran wanted payment in gold from India.
Once the Iranian crude can reach the general market, prices will either have to soften or production will have to be systematically throttled back (and that means, Saudi Arabia). Zero et al have been trying to prevent growth in US production and have only managed to slow it down a little. If crude drops much below $100/bbl, fracking expansion plans will go on hold, Keystone XL will never get done, etc.
