This has been reported for years now, but Adam Housley has more details:
My military and Department of Homeland Security contacts are insistent…it’s not if Hezbollah operatives have been smuggled into the U.S….but how many? They note that drug tunnels are becoming much more sophisticated and striking similar as tunnels being used by terror organizations to smuggle weapons into the Gaza Strip. My contacts also say they have real concern that bombing techniques used in the Middle East to promote terror are now also being used inside Mexico, as the cartels war with each other and anyone in their way.
Wait a minute. I thought global warming was the problem. My bad.
