My question is if he were president with a sympathetic majorities in the house and senate, what would you do . First of all, take stock there is an assumption in the americans Global Leadership in requires an American Military presence. But to examine parts of the world. Let me break it down specifically. When that commitment was made within 30 days of the cold war western europe was weak and vulnerable. And it made sense it provided a basis for western europe for democracy to take hold in 2016 they dont need as. They are richer than we are. Democracy is well established but they dont bother to maintain any significant military force not to say the chips are coming on next tuesday but by 2026 we are out if you want to maintain and the nato alliance, goahead bin is the european alliance. They make the point there comes a time when the mission is accomplished and the United States can come home. We have tremendous change happening with revelry producing conflict on a large scale whole i would argue it is a stabilizing factor for the effect to be destabilizing for those that would acquire a Nuclear Weapon and one could see a destabilizing process to occur. And seems to me our presence is counterproductive the focus of military attention is less stable today they and when we began. There are those who say that means we should try harder but i believe that there is said need to demilitarize. How . To get nations in the region to take responsibility for separation of responsibility. How . Isis poses an existential threat to countries which have all kinds of reasons not to calabria or corroborate and were they to do so with the 25,000 tons. The task is to bring those countries to recognize the common interest. I am saying it offers examples of breaker a collaboration occurs right road were to world war ii where the imperial Great Britain and the totalitarian from the soviet union will set assad their differences. We have time for one more question. Tavis use of private contractors in afghanistan inhibit the success of nationbuilding . The question should be how did it come to be . That windy iraq and afghanistan wars the number of private security contractors outnumbered the u. S. Troops . How does that come to be . Looking at the unintended consequences to rely on the all volunteer force then the conditions of permanent war we ended up two more years as a policy makers and the pentagon turned to the notion of defense contractors to fill the gap at a very high cost and i argue with little evidence that they were worth the money. I know you will sign books. Thanks. [applause] we barely scratched the surface i encourage you to pick up a copy will have an indepth and somewhat pessimistic understanding of the war in the middle east. [inaudible conversations] dash is thereby explaining myself how life began to write this book was set to mexico in 2010 i thought i would write about ordinary subjects like a regular business our oil or cars or tourism. But just as i rise of the drug war arrived in it was that time when the murder rate what was spiraling in almost doubled in the space of a few years. Quickly this is what people want to think about. Like the Business Roundtable to find it was the subject of the drugs business. Cry got into the habit of business stories one we can drug habit the next then i came to see that it wasnt quite the difference that you might think and wonder if it was the big business story we were missing. So i will give an example where was an extraordinary case a the government sought a gigantic cash of marijuana in merit more than 100 tons they found in a warehouse on the edge of the city. They made a gigantic bonfire with gasoline to set it on fire the police were there to be sure nobody was the ending downwind like the 100ton joint. [laughter] it was widely reported at the time that this represented of about half a billion dollars and that is how much this was valued at. But i gave it some thought and it seemed that was high. There are not Many Companies in the world can handle that shock that a drug cartel is big but not that big but i would look at the estimate. It is fairly straight forward but they figured out the retail price to the states and estimated 75 a gram over 100 tons and arrived at the figure and it sounds plausible but think again you can see imagine if you do this like coffee. The retail price is a cup of coffee is 4. And you get 2 grams of coffee so that means a kilo of coffee is worth 2,000 per gore mentioned trying to calculate the price of a cow. You get to a weird for your. So i did a rough calculation using wholesale prices that are much lower and also the price is about 0. 8 per gram. So it may be worth ted million rather than 500 million. It shocks me and makes me think that what were doing on the supply side is 90 percent less of an investment and what else are we getting wrong . So seriously and went to look at it as a business thnd
