The First Two Oil Shocks In 1973, Israel was battling Egypt and Syria in the Yom Kippur War.
In response to US support for Israel, the Organization of the Petroleum Exporting Countries (OPEC) placed an embargo on oil exports to the US and several other countries.
The second oil shock started in 1979.
This attack, and other recent ones, killed dozens of Syrian and Iranian soldiers.
A few days later, President Trump pulled out of the 2015 Iran nuclear deal.
