What's The Deal With Emergency Broadcasts?

5 or 6 times a day? How about 5-6 times within an hour today approx 1pm CDT - not to mention all the ones at other times of the day & in the middle of the night. What is going on? Are all of these recent pick-up testings due to the Iran oil situation or N Korea? China will back either country, if the US does anything to them. Anyone out there have any military input to these drastic increases in the emergency broadcasts? to post by Bobbo
