I am convinced the terrorists will use the Southern border before they use commercial plane flights for one reason: using the border, they can also bring across the tools they need to perform their nasty deeds. None of those items would make it on a commercial airliner.
I am, quite frankly, anxious to hear nobama’s explanation after some terrorist group does some nasty deed here in America and it is proved they came in over the border.
Where will they acquire these tools you refer to? How would they have gotten them into Mexico? Are those supplies not readily available here (think OK city bombing)?
“using the border, they can also bring across the tools they need to perform their nasty deeds”
OK, so ISIS must realize that if they set off a few car bombs it will only provoke a greater military response from the US.
The only way the Caliphate will obtain its expansionist goal is to render the US unable to respond.
They need to hit us big, both bioengineered plague or ebola, wipe out the power grid with an electromagnet pulse weapon or smuggle in some mini nukes to place in all of our major cities.
