This is the most consequential geopolitical development this year. All are U.S. allies; both Saudi Arabia and Qatar are known to have funded and supported Islamic State and other terrorist organizations in the Middle East. They have even been fighting as allies in a war in Yemen, and yet Saudi Arabia has cited concerns over terrorist funding as the reason they are cutting ties with Qatar.
It is highly unlikely that these four states would be turning on Qatar without approval from the Trump administration.
