GLADIO already sent its warnings, see the graphics on my webpage. Such peaks were in 2017, very regular to warn terror attacks in the Western countries. Several terror attacks in UK, France, USA have been warned with such peak with a beveled tip. We call that the sword shape. Thanks to such alerts, I warned 7 times the authorities of an imminent terror attack, including the bomb attack on May 22, 2017, Manchester. Today May 21, 2018, GLADIO sent 2 peaks and this never occurred before! So, I believe that the next attack could be very important and probably on May 22. Please take a look at my webpage to see the alert peaks from GLADIO. http://www.gladio-activities.net.
Of course, I can mistake, or misunderstood the communication from GLADIO, but usually, I was all the time right even, if the attacks were sometimes delayed for some days, after the warning.
On this webpage, you will also see the peak for the Texas shooting.
