Presidents (any president) don’t make micro-managing tactical or strategic decisions for the military. The Joint Chiefs advise the president on major military policy courses of action and they present options for the president to select between. They would not advise on a specific domestic training exercise. If Governor Abbott was to request that Jade Helm br moved out of his state, that might get to the Joint Chiefs’ level and then to Obama, or if Congress was to request that the excercise be cancelled altogether.
With as many hard core conservatives as there are in the Special Forces units (Green Berets, Seals, Air Force special ops) that will be involved in Jade Helm 15, you can bet that there would/will be anonymous leaks to the conservative media if anythng untoward is/was going on.
With as many hard core conservatives as there are in the Special Forces units...Sorry, but these guys want to eat and support their families, too. Don’t count on anything, expect the worst and rely on yourself.
