The military is under obligation NOT to obey orders to blow up the country.
Obama could call up his friends the Iranians, North Koreans, or maybe some of those Manpads, or maybe some of the military firepower we gave to ISIS, or...... you name it. One little EMP is all it would take.
Or he could have his communist-Islamist buddies make another run on the bank, sending us into martial law and all those DHS hollow-point bullets and body bags come in handy.
Or he could let all the Hamas and Hezbollah operatives who were flown in direct flights from Iran to Venezuela come in through our southern border, set up camp in every state’s capital city, and put bio weapons in our drinking water.
Or you name it.
He doesn’t have to use the military. In fact, he could keep everything secret from the military and the only sign that he might blow things up is the connections he’s had with OTHER people who have attacked America - stuff like funding, arming, training, harboring, defending, releasing, excusing, etc those who have said they will destroy this country, be it folks like Bill Ayers or folks like the 5 Gitmo guys (and the “known terrorist”-classified Saudi “person of interest” in the Boston Marathon bombing) he set free or the cartel-allied Hezbollah and Hamas agents he’s been keeping our southern door wide open for, for the past 5 years.
When the military sees somebody who has a FANTASTIC opportunity to destroy the country, has spent his whole life aligned with those who have sworn to destroy the country, and who has funded, trained, equipped, harbored, set free, defended, etc those sworn to destroy the country .... what obligation do they have?
Let’s say somebody who matched that description was a pilot on a plane with 500 passengers on board and he’d already done a dry run of an attack. Who could do anything about it, and under what authorization from the Constitution?
