My Step-Dad... H.W., Ret. A.F Msgt.. (God rest his soul)...use to tell us that the biggest threat to this country was to the south of us. This was during Iran-contra crappola.... He was right. He said we had the equivalent of the Israeli-Palestinian conflict only driven by drug lords - right on the edge of our country with NO protection for the violence spilling over into the USA. He was right. He passed away in the late 1980's.
(You were a wise man H.W.... God bless you).
