America is governed by a drunk monkey.
At the moment the US is governed by a president with no knowledge of foreign affairs and without any inclination to learn. He only reacts. He is like the proverbial drunk monkey in a cage with a scorpion. Sometimes he is happy and makes stupid mistakes. Sometimes he gets stung and gets angry and makes stupid mistakes.
The monkey is supported by the wealthy who benefit from his "reforms" - tax reform, deregulation, appointment of billionaires on his board. He is also supported by politicians, mostly Republican, who would sell their grandmothers rather than lose their positions and by some elements in Russia, Israel, Iran, China, the "alt-right" in Europe, etc.
American policy is swerving like a computer-controlled automobile that has a broken chip in its executive protocols.
He governs by "chaos", his friends say. He insults the short, fat dictator of North Korea - then calls him his best friend. He insults allies and close neighbors, then tries to make it up to them with a few disingenuous kind words. He spews out racist comments and then says he is the least racist person you have ever met. He smashes trade agreements, environmental agreements, mutual defense agreements, anything that can gain him the support of the loony tunes crowd.
Is it any wonder that the US policy toward the Kurdish question is a jumble? Even the most brilliant observers cannot understand the internal and external factors at play in that ethnic group with ambitions to self-government. It is as Lord Palmerston once said about an earlier European problem of national identity:
“The Schleswig-Holstein question is so complicated, only three men in Europe have ever understood it. One was Prince Albert, who is dead. The second was a German professor who became mad. I am the third and I have forgotten all about it.”
Even if it were possible to wean the President off TV news and Tweeter, there is no chance that the chaos would abate. Chaos is not a policy. It is the extremely dangerous by-product of willful ignorance and lack of impulse control.
