"You apparently agree with those who say that mustard gas in Tikrit is a threat to you here."

Not just mustard gas but VX ect ect. Or even a bio weapon. For some of the reasons you gave yourself. Open boarders and ports as you mentioned.

Then the issue would seem to be one of what works. We quite obviously don't even know where all in the world this stuff might be, nor what the sympathies might be of all who possess it. So the concept of going and getting it all does not hold up as a viable solution. But directing efforts toward stopping them, whoever they may be, from bringing it here certainly would make good sense. Amazing how much it is ignored in the public discourse.
