We've been very fortunate here in the U.S. Can't account for our good luck -other than a few "incidents" (sorry to use a belittling word, but).

Our good fortune will surely run out. Our borders are a sieve, we have many citizens that are sympathetic to these M.E. terror groups and hate the U.S., a plethora of weapons and worse easily available, generally empathetic public, and unbridled social media gone wild.
Let's face it folks - it would not take much for an infiltrated group to marshall their resources and do their dirty deeds across our country. I could go on but won't. Simply too scary; I always say I'm glad I'm my age as this war ('course the WH simply cannot say it) will spread even more and be decades. Hate that our kids and grandkids are in for this in their lifetimes.
