Gen. Martin Dempsey took a cautious approach to U.S. involvement in Afghanistan and Syria. He did not approve of the way Gen. McChrystal expanded U.S. involvement in Afghanistan, and the hasty manner in which the Iraqi army was trained under his predecessors leading to some commanders being appointed who later became members of sectarian death squads. Under his command the U.S. limited its role in Afghanistan and Iraq and handed more responsibility to local forces. Gen. Dunford who succeeded Dempsey as chairman Joint Chiefs of Staff for the U.S. follows the cautious approach set by Dempsey. Dempsey's approach extends to what he believes is an Heisenberg effect in physics where when you you observe or touch something it changes the way it functions and operates. For critics such as Senator McCain, who served in Vietnam as a pilot, if Dempsey did not want to intervene in some country, he could invent the reasons not to get involved. President Obama exceeded the caution exercized by Dempsey, leading to a situation where the U.S. after hasty action under a Republican president seemed to lurch in the opposite direction under his Democratic successor by not taking action where U.S. presence was needed, followed by a corrective course to make up for this....

This WSJ editorial points out that the lack of action from the Obama administration has led to the current situation in the Middle East with Russian intervention, the wave of refugees from Syria, and the increasing sectarian conflict. It cites from president Obama's address to the UN General Assembly that "the nations of the world cannot return to the old ways of conflict and coercion," yet failing to take action in the Middle East to prevent this from happening.

Obama's comments during a visit to Greece about the challenges facing multiracial and multicultural societies such as the U.S. and the people left behind through globalization. He says "we are going to have to guard against a rise in a crude sort of nationalism or ethnic identity or tribalism that is built around an "us" and a "them."  Obama also referred to a global elite "that seems to live by a different set of rules, such as being able to avoid taxes," which he said "fuels a feeling that globalization only benefits those at the top," and leads to a push back from people who feel they are losing control over their future." The problem for workers is that fewer and fewer workers are needed in todays advanced automated factories and manufacturing moves across borders leading to anxiety. The president may have realized the extent of the damage only in the closing days of the campaign in 2016, because of his support for trade agreements without talking in this manner about the lives of workers.  ...

Prof. Gorton and Prof. Metrick of the Yale School of Management review 16 scholarly studies and papers on the causes of the 2008-2009 global financial crisis in the current isue of the Journal of Economic Literature. Another article in the same journal reviews 21 books on the subject. Samuelson says the most cited causes- lax regulation and passive regulators, and the policy of home ownership that encourage the packaging and of securitization of mortgages to government sponsored agencies Fannie Mae and Freddie Mac- are only the surface causes. If we are to explain how a whole society seemed to believe in the idea that somehow there was a way to maintain a rising tide continuously, with only small corrections over several decades, by the clever manipulation of monetary and fiscal policies; then one has to look to the hubris of economists who acted as if this was possible and the gullibility of business and a public that desperately wanted to believe as some have put it "that this time it was different," or that shrewd management of economic policy could actually bring about such a panacea. The abiding lesson is economic policies based on a better understanding of how modern industrial economies work are merely useful tools, no more no less, and there is no substitute for a good ethic, wise management and careful thinking on the part of the public, business and government, particularly for the people in leadership positions. ...
